How Accurate is SIG P320?
When tested against similar pistols like the Glock 19, the SIG P320 does an excellent job keeping the shooting groups nice and tight. At about 10 to 25 yards, the shooting groups were an inch apart from each other. The accuracy was consistent and doesn’t go all over the place as long as you have total control over your pistol. In the shooting test, both the SIG P320 and the Glock 19 were almost identical in terms of accuracy.
Types of SIG Accessories
There are some SIG P320 accessories that will work to your advantage. That is, unless you don’t need them. You want your pistol to be in tip-top shape so you can make it as accurate and reliable as possible. But what kind of accessories are the best in doing that? Here is a sample list of the most popular accessories currently on the market:
Magazine/Magazine Extension
The magazine will house a standard capacity of 15 rounds. However, some magazines will carry fewer rounds, while others will carry more. It will usually depend on your personal needs and preferences. If you believe you need a few extra rounds on your current magazine, you can add on a magazine extension.
This type of product will boost your round count up to about four rounds. Usually, they can be used for applications like target and competition shooting. However, concealed carry users were able to use it for their EDC use without compromising their ability to carry concealed.
Sights
Accuracy is really important, especially when you’re using a pistol best designed for concealed carry and self-defense purposes. But it will also be great to have if you’re in a target or competitive shooting application. Either way, you need excellent sights in order to get the best possible accuracy. You can settle for a set of rear and front sights together or go with a standalone if you’re more comfortable.
Holster
If you conceal carry, having a holster for your pistol is a must, especially when conceal carry laws require you to have it in a holster when in a public setting. You’ll need a holster that will keep the pistol secure and not allow it to easily slip out.
Holsters are available in outside-the-waistband (OWB), inside-the-waistband (IWB), and with shoulder straps. Each will have its own advantages and disadvantages of use, but it will depend on how much overall concealability you need for your P320.
Which Accessory is Best For Me?
The short answer to this question is, it depends. It depends on your personal needs and preferences. What accessory is best if you want better concealability? Do you need a new magazine with more rounds or will an extension be enough? These are some of the questions that get asked a lot. Fortunately, you’ll be able to find the answers here. Let’s outline each common situation and match it with the accessory you’ll need:
More (or Less) Rounds?
Do you think 15 round is not enough? If so, there are two options that you can choose from. The easiest thing to do is to get a magazine with an increased round count. There are those with a capacity of 17 or even 32 (whichever you prefer). The same can be said if you want fewer rounds.
There are 10 or even 12-count capacities to choose from if you are looking to carry less rounds. However, if you simply need a few extra rounds without having to purchase a single magazine, a magazine extension will come in handy and fit your need perfectly.
Better Concealability
The P320 pistol is by far one of the best in concealability. In fact, it’s probably one of the most concealable pistols on the market and thus, is a favorite among concealed-carry practitioners. If you want the best concealability possible and to keep your pistol out of plain sight, an IWB holster might do you some good.
Better Grip and Control
For most, the P320 is easy to handle and control. However, you may be susceptible to having it slip out of your hands if you tend to have sweaty hands. In a situation where stress is high, this is the last thing you want to happen. And it can put you in some pretty dangerous situations.
That’s why it is important to invest in a good grip that will give you maximum control. Talon grips might also come in handy if you want the absolute best possible grip. They are weather and sweat-resistant and won’t easily allow for slippage.
Review of the Best SIG P320 Accessories and Upgrades
The following are the top nine SIG P320 accessories and upgrades available on the market today. Each is considered the best in its class (best grip, best magazine, etc.). It is important for you to keep an eye on the features and characteristics of every accessory you’ll be looking at.
This way, it will give you a good idea of how you want your pistol to function. You can choose one accessory or multiple types, depending on your personal needs and preferences. Now, let’s take a look at the first accessory on our list, our “best overall” SIG P320 accessory and upgrade:
Best Overall:
P320 T-Comp
Pros
Cons
What Recent Buyers Report
The Tyrant Sig Sauer P320 Compensator, also called the P320 T-Comp, amazed us with the burst of positive reviews on multiple sites.
Most users reported increased quality target re-acquisition with their sensed coil and reduced muzzle rise. Recent buyers are also pleased with the relatively smaller size of the model.
Why it Stands Out to Us
Almost all of the compensators from Tyrant claim perfect and easy assembly on your firearm, but what caught our eye with P320 T-Comp is the fact that it fits into all open-ended holsters. So, you don't have to buy any additional holster after its installation.
This saves not only your time but also your energy that might have been spent on a difficult installation.
Who Will Use This Most
The diversity that the Sig Sauer P320 offers is incredible. It can be used in compliance with any 9mm firearm.
So, if you are a professional shooter or a range day goer, the P320 is your best option in the market in terms of quality. It is also a good model for amateurs because it doesn’t require too much practice to perfect.
Bottom Line
We understand that the Sig Sauer P320 is a little expensive as compared to its market competitors, but the quality of the compensator makes it the more convenient option. A great feature of this compensator is that it does not require any cleaning and thus makes it a good choice for those who don't want to strip their gun down so often.
Runner-up:
TRUGLO TFO Handgun Sight Set
Pros
Cons
What Recent Buyers Report
A lot of recent buyers were satisfied with this sight. It’s bright, visible in any lighting condition, and just so happens to be usable by just about anyone. One older shooter with poor eyesight was able to see a lot better with this sight compared to a red dot sight that he had used for years. He says he was able to shoot with and without his glasses and still get consistently accurate shots.
What Recent Buyers Report
This sight is tough, bright, and delivers on the promise when it comes to accuracy. It’s all you’ll ever need in a pistol sight. Plus, it glows in the dark and gives you an advantage in low-light or near darkness. Best of all, it’s not battery-powered. This is the perfect sight to use in self-defense situations at night.
Who Will Use This Most
This sight will be used most by concealed carry users, especially when they’re looking for a sight that will get them through the day or night in the situations that matter most. You’ll be confident in knowing you have a sight that is reliable and accurate while you’re using it.
What Could Be Improved and Why
One of the possible improvements that should be considered is making sure that the front sight manages to stay intact from the beginning. Some users have complained about the sight holding up for the short term only to fall off after it’s been in and out of the holster so many times. Make it so the sight sticks to the pistol like super glue.
Bottom Line
If you’re looking for an excellent sight that will deliver excellent accuracy and is visible in any light condition, you’ll love the TRUGLO TFO Handgun Sight Set. This sight is not only accurate, but also proves its undying loyalty in being very reliable in situations where it matters most.
Best for the Money:
Real Avid Gun Boss Handgun Cleaning Kit
Pros
Cons
What Recent Buyers Report
A lot of recent buyers were looking for a simple cleaning kit for their P320 pistol. Most were happy with what they’ve got. The cleaning rods were decent and the pads did their jobs brilliantly in cleaning out all the residue and gunk. One user said it was the easiest cleaning kit that he’s used in a long time. Everything is organized and has exactly what is needed to clean and maintain their pistol.
What Recent Buyers Report
This kit is good enough for cleaning many pistols of various calibers. Since the P320 fits that category, this kit will be enough. It has the parts you need to ensure that you can easily clean your pistol in a matter of minutes. You won’t have to deal with complicated layouts. Just a simple, basic kit with everything you need.
Who Will Use This Most
This will be used by your regular pistol owners and by those who conceal carry and also use their pistol on a regular basis or on weekend target shooting sessions. At some point, you’re going to need to clean your pistol to ensure that it’s in excellent shape and won’t give you any reliability issues down the road.
What Could Be Improved and Why
Despite the cleaning rods being of decent condition, they should be a bit more solid and sturdier. They won’t break easily, but they feel quite flimsy to the point where some users are afraid that they will actually break them in two. Make them nice and sturdy so it gets rid of that “cheap quality” feeling.
Bottom Line
If you want a cleaning kit that is well-organized and enough to take care of your common pistol cleaning needs, you’ll need a kit like the Real Avid Gun Boss to do its magic. A good pistol is a clean pistol. And a great cleaning kit like this will definitely keep it in shape and ready to handle any task.
4. Streamlight TLR-4 Tactical Light with Laser Sight
Pros
Cons
What Recent Buyers Report
Most recent buyers were quite happy with the light (and the laser) itself. It’s ridiculously accurate and really does a good job when the users were in a low-light setting. They were able to move quickly around dark corners, therefore, giving them an advantage over those who dare invade their home. One user said that he was confident that once this light was attached to his pistol, it was ready for primetime.
What Recent Buyers Report
This is probably one of the best combinations you can get: a bright flashlight and a laser sight rolled into one. It would be nearly impossible to install them individually on a small pistol like this. It’s a design that kills two birds with one stone. On top of that, you don’t have to hold a flashlight in your free hand and your pistol in the other. If you need a flashlight plus an accurate sight, this will definitely a perfect accessory for your weapon.
Who Will Use This Most
This will be used by those who are tired of having to hold a flashlight in one hand while using their handgun in the other. It will solve a major problem and make navigation a whole lot easier for those who want to get around in a low-light situation and gain a tactical advantage over home invaders and night prowlers without having to bump into anything.
What Could Be Improved and Why
A potential improvement could be to figure out why the laser sight doesn't hold zero. However, it would be wise to zero it the moment you have it installed. This way, it will give you the ability to test it out and see how far you can go with it before having to zero it again. It can be easy to sight in within minutes or even a couple of hours (depending on how far you want it to go).
Bottom Line
If you’re looking for an affordable upgrade for your P320 pistol, the Streamlight Compact Rail Tactical Light will serve as your best possible option if you’re looking for both a bright flashlight and a pretty decent laser light sight. When the two work together, you have quite the unstoppable force.
Best SIG P320 Magazine Extension:
Taylor Freelance - SIG P320 +5 Base Pad
Pros
Cons
What Recent Buyers Report
A lot of recent buyers were able to use this to extend their magazines by a few rounds. One user was using it for his 9 mm magazine because he wasn’t satisfied with having only 12 rounds. It was a worthy addition to his pistol, he said. Plus, it’s concealed carry-friendly and doesn’t bulge up his holster.
What Recent Buyers Report
A good magazine extension will definitely work to your advantage in order to prep your pistol for some applications. More specifically, this is best used if you’re shooting targets or prepping for a competition. The more rounds you have, the better off you are. This extension is solid and has the ability to fit your pistol and increase its firepower by quite a bit.
Who Will Use This Most
This will be an excellent addition to your pistol if you’re either a target shooter or a competitive shooter. But don’t discount this as a useless accessory for those who conceal carry. It definitely helps if you want to add a little extra firepower to your pistol. Who says there is such a thing as too many rounds?
What Could Be Improved and Why
A possible suggestion would be to make the spring a little sturdier so it can handle the weight of other caliber rounds (more specifically while the magazine is fully loaded). Even a consistently fully-loaded magazine can wear down the spring a little bit and lead to reliability issues. Strengthening it a bit may make it last a bit longer.
Bottom Line
If your magazine’s capacity isn’t enough, you can extend it by a couple of rounds fairly easily. The Taylor Freelance magazine extension is probably your best bet when it comes to finding a unit that will give you a little bit more firepower than standard. If you need a few more rounds, a great extension might just get the job done.
Best SIG P320 Grip Module:
Sig Grip P320 9/40/357 Grip Module Assembly
Pros
Cons
What Recent Buyers Report
Most recent buyers were looking for something that will give them a better grip on their pistol. Not only that, they wanted something that would give their pistol a more solid frame and make it even tougher to break or damage. These buyers did not walk away disappointed. They were able to grip the pistol nicely and kept control of it, even in bad weather conditions.
What Recent Buyers Report
This grip covers a good part of the pistol. Aside from getting a good grip, you’ll also get the frame beefed up a bit. This way, it makes it a bit tougher than a P320 that just rolled off the assembly line. Plus, you can easily make your pistol tougher than nails. Just get the right kind of tools and you'll have this installed on your pistol in a matter of minutes.
Who Will Use This Most
This will be used for every day carry. It is a useful upgrade for those that want to improve the quality and aesthetics of the pistol itself. Meanwhile, it will also make the pistol’s overall grip better so it won’t be able to slip and slide around in bad weather conditions.
What Could Be Improved and Why
One of the things that should be done before this grip hits the shelf would be to check for sharp edges. This way, it will reduce the number of cuts to the holster (depending on which material it’s made from). Sharp edges can cut some holsters, which may lead to snagging when you’re trying to get the pistol out of the holster itself.
Bottom Line
If you want a better grip on your pistol, the SIG Grip is exactly what you need to make your pistol grip feel like you’re holding on to flypaper while shooting. Whether your palms sweat or you’re outdoors in bad weather, you get a superior grip on your pistol, no matter what.
Best SIG P320 Holster:
MFT Holster Sig Sauer P320 Full Size OWB Holster
Pros
Cons
What Recent Buyers Report
Most recent buyers were satisfied with this holster. They loved how versatile it was and allowed for either OWB or IWB carry. The preferences for one or the other was obvious: some liked carrying OWB and others liked IWB. One user even said he couldn’t decide on which was better for him, but ultimately ended up carrying it inside-the-waistband since it provided him with the best coverage and comfort.
What Recent Buyers Report
The OWB and IWB abilities are, by far, one of the most remarkable features that no another holster has ever matched at this point. This definitely saves a lot of time and money for those who cannot decide on whether to choose a standalone OWB or IWB holster. This gives them the chance to at least try them both and decide which is better for them.
Who Will Use This Most
This will be used by concealed carry practitioners that want an excellent holster that makes enables better concealability. Regardless of if you use it outside or inside-the-waistband, you get maximum concealability that will be hard to match with any other holster on the market, especially with a pistol like the P320.
What Could Be Improved and Why
One inclusion would be to add a belt just in case it is used for OWB carry. Even if you carry inside-the-waistband, the belt can be worn just like a regular everyday accessory. Regardless, it will be useful one way or another.
Bottom Line
If you want a holster and you cannot decide between OWB and IWB, why not choose both and give this product a try? The MFT Holster by Sig Sauer will give you the opportunity to carry either way so you can choose which one is more comfortable for you.
Best SIG P320 Trigger:
Apex Tactical Specialties Inc - Sig Sauer P320 Action Enhancement Trigger
Pros
Cons
What Recent Buyers Report
A lot of recent buyers wanted a trigger that was nice and smooth. At the same time, they wanted one that allowed for quick and easy shooting and follow-up shots. The new users got exactly what they wanted out of this trigger. One user said he never gets tired of it, even after a long day at the range.
What Recent Buyers Report
This trigger is a straightforward design and is not curved like most triggers you see on pistols. But the construction and design are solid and ergonomically-friendly for most shooters. Plus, the pull weight is nearly 20 percent less than the average factory issued trigger on a P320.
Who Will Use This Most
This will be used by P320 users that want a lighter trigger pull and quick follow-up shots in the process. This will fit perfectly for every day carry and target shooting applications. Plus, it’s best for those who want to say goodbye to trigger finger fatigue after an extended shooting session.
What Could Be Improved and Why
A possible improvement would be to at least lighten the pull weight a bit more. This way, it can make pistols a little more competition-friendly. Despite the weight reduction, we feel like it might be a little too heavy for competitive shooters.
Bottom Line
If a trigger upgrade is what you need, the Apex Tactical Trigger will probably be the best possible choice. It’s easy to pull, solid in construction, and will definitely work to your advantage if you want quicker shooting and even quicker follow-up shots.
Best SIG P320 Magazine:
Sig Sauer P320 / P250 Fullsize 9 mm Magazine
Pros
Cons
What Recent Buyers Report
A lot of recent buyers were satisfied with this magazine. With ten rounds at their disposal, it’s enough to get by in an EDC application. One user said he had more than enough shots, just in case he has to use them. It was easy to load and lace inside the mag well of the pistol.
What Recent Buyers Report
This magazine is tough enough to handle all kinds of hard surface impacts. This means the magazine can free-fall and hit the pavement or a hardened floor without busting apart. Not only is this a huge plus for users, but it’s definitely a must for every pistol magazine. Plus, you’ll never know how many mags you’ll need for your desired application (we’re talking how many shots you need, plus extras in case one of your magazines malfunctions).
Who Will Use This Most
This magazine will likely be used for any purpose. Concealed carry, casual target practice, or competitive shooting will be your top three ideal uses. With ten rounds at your disposal, it’s just enough to have handy in case you need to use it. But for target practice, it’s the ideal count to have if you’re planning on going through extra magazines. Ten rounds is a decent amount to have in each mag.
What Could Be Improved and Why
Despite no obvious cons, there is one thing that could be addressed. If you intend to clean and maintain the magazine itself, you must be aware that disassembly and reassembly might be a possible issue for some users. Be sure to keep all small parts off to the side and together while disassembling and cleaning your magazine so they won’t get lost.
Bottom Line
If you’re looking for a good solid magazine with a decent amount of firepower to work with, the Sig Sauer P320/P250 full-size 9 mm magazine might be exactly what you need. No matter which application you use your pistol for, it’s always good to have a magazine that is reliable and fulfills all your concealed carry needs.
Best P320 Sig Threaded Barrel:
Silencerco - SIG P320 Threaded Barrel 9 MM 1/2-28
Pros
Cons
What Recent Buyers Report
A lot of recent buyers were satisfied with the barrel. They even stated that this made their pistols much more accurate than their previous factory-made barrel. One of them was able to install a silencer for self-defense purposes without any issue. He says that he feels a lot stealthier than ever.
What Recent Buyers Report
A pistol barrel will definitely play a huge role in overall accuracy. Sometimes, a factory-made barrel is something that can be a disappointment when it comes to the accuracy of your pistol. This is a solidly-constructed barrel that can fit most silencers, which is a welcome ability for most concealed carry practitioners.
Who Will Use This Most
This will be an excellent barrel for those who use their pistols for self-defense purposes. It is even better for them when they want added stealth to give themselves an advantage over home invaders and prowlers. It’s definitely useful for those who want to take out attackers without making much noise.
What Could Be Improved and Why
Since the P320 comes in different calibers, there should be an option where there is a barrel for specific calibers, as well. You have a SIG P320 but it’s a .45? Then why not get a barrel that will be compatible with those rounds (and silencers that fit such calibers themselves).
Bottom Line
The Silencerco SIG P320 Threaded Barrel is your best possible choice if you’re looking to upgrade your accuracy or want to add a little “silence” to your pistol for some applications. It’s great for self-defense and even tactical situations where it’s legally allowed.
Perks of Getting a Few Upgrades
If you choose not to add some great upgrades to your SIG P320, you’re definitely missing out on a lot of advantages. Knowing what to upgrade and which accessories to use will give your pistol the best performance possible. Here’s what you’ll get to enjoy:
Better Accuracy
It’s no secret that accuracy is one of the top attributes of any firearm, especially when you want it to function optimally in most applications. Find a great sight, barrel, or both if you want to maximize your pistol’s ability to shoot tighter groups consistently.
Quicker Shooting
Accuracy is one thing, but getting a shot off quickly is another. Timing is everything when it comes to using your pistol. If you want to shoot at a target quickly, it’s important to find a trigger that will be light in pull weight. Also, a crisp trigger with an easy reset is just another added bonus you’ll really want.
Better Concealability
The P320 is one of the best pistols you’ll ever want when it comes to concealability. Yet, it would be even better if you purchased a holster to keep your pistol nice and safe wherever you go. If you want the best in concealability, nothing comes closer than an inside-the-waistband (IWB) holster that will really make the difference.
Conclusion
The best SIG P320 accessories and upgrades are at your disposal. It all depends on what you want to upgrade and what you want to leave alone. Remember, your pistol as-is might not deliver the best performance. If you feel like it needs some upgrades, don’t be afraid to poke around to see which accessories will make it stand out much better.
