What Size Magazine Do I Need?

The short answer: it depends. It will depend on how many rounds you’ll be needing for all of your shooting needs. Keep in mind that the more rounds that you have in one single magazine, the larger the size. In other words, a 15-round magazine will be larger in size compared to one that contains 10 rounds. The size that you need may also be determined by your intended application.

What Should I Look For When Buying Sig P365 Magazines?

When looking for magazines that will be best for your Sig P365, you need to keep your eyes open for a few important features and aspects. This is especially true when you are looking for something that you know will be useful to you in the long-term. Here are some things you need to look for when purchasing a magazine:


Of course, we begin with the price tag. It might not be a worry to someone who has plenty of money to work with, but granted, the budget shopper will always pay close attention to it. If you are on a budget, the price could be a very important factor. However, you should always check to make sure that the quality is not cheap and flimsy so you know it’s the best that you can afford. Never sacrifice quality because of a cheap price tag.


If there is one thing you absolutely need to have in a magazine, it’s reliability. If it jams or malfunctions, chances are it will be rendered useless. This is one of the reasons why we highly recommend that you buy multiples of the same magazine once you have had enough time to try out the initial magazine you’ve chosen.


All the magazines that you’ll find will need to be high in quality. This means it will need to be able to hit hard surfaces multiple times when emptied and still be able to work no matter how hard they hit. You don’t want your magazine to hit the hard surface and have the inner workings busted up, right? You’ll get that in cheap and flimsy magazines, but with the magazines on our list, that won’t happen. 

Review of the Best Sig P365 Magazines

The following are our reviews of the best Sig P365 magazines currently on the market. Let’s begin by taking a look at the “best overall” Sig P365 magazine on our list:

Best Overall:
SIG Sauer P365 Micro Compact 10-rd Flat Base Magazine


  • Easy to load
  • Really durable
  • Fits on most P365 pistols
  • Perfect for self-defense applications
  • Reliable through thousands of rounds; doesn’t jam or malfunction


  • None

What Recent Buyers Report

New users found this magazine to be quite small in size, but easy to store in magazine pouches in their holsters or tactical belts. They also concluded that it was easy to load quickly so they were able to rely on their hands more rather than speed loaders. One user said that despite his limited mobility in his hands, he was able to take his time and load this magazine quite easily without any issue. 

Why it Stands Out to Us

Ten rounds are plenty enough if you are looking for something that will make sure you can ward off a bad guy that dares to mess with you. With that many rounds at your disposal, you can take out one with at least a couple of shots, but it’s good to have the confidence in knowing that you are prepared for any surprises. Quality-wise, the construction is solid and able to absorb any shock stemming from hard surface impact. 

Who Will Use This Most

This will be the perfect magazine for anyone who could be looking for something that will get them through a dangerous situation. If 10 rounds are enough for you, then by all means consider choosing this magazine for all your EDC carrying needs. Plus, you get a magazine that gives you excellent reliability that is hard to match (along with quality that really stands out). 

Bottom Line

The Sig Sauer P365 Micro Compact 9mm Magazine is solid in quality, easy to maintain and clean, and definitely gives you the best chance of making sure that you come out on top against any assailants that are stupid enough to attack you or your family. Be it at home or while you are out and about you will be ready for the dangers that threaten you. 

Best for the Money:
SIG Sauer P365 Micro Compact 9mm Steel Pistol Magazine


  • Superior quality
  • Loads up pretty easily
  • Affordable for most budgets
  • Easy cleaning and maintenance
  • Perfect for self-defense shooters


  • May be difficult to load the last two rounds
  • May have a hard time fully releasing at times
  • No follower to indicate how much you have in the magazine itself

What Recent Buyers Report

A lot of users were looking for an affordable magazine that went well above and beyond expectations. Sure enough, they were pretty impressed to know that this magazine did exactly that. This was compact in size, making it a perfect fit for P365 pistols. One user said that he managed to keep extras in his tactical vest since he uses it for both self-defense and casual target shooting.

Why It Stands Out To Us

Here, we take a look at a magazine that is small in size and very easy to conceal in magazine pouches. It’s the perfect size that won’t print. So, if you are looking for a magazine that will fit in pouches or even pockets until you need them, these could be what you need. Plus, they are able to handle different brands of 9mm rounds, always a plus if you have a mixture of rounds laying around.

Who Will Use This Most

If you are looking for an affordable option for a self-defense magazine, then you should certainly give this a good look. Yes, the quality is outstanding and the performance exceeds expectations. It’s far more than you could expect to get out of a magazine that is considered a “budget” option; believe us when we tell you that you are going to get a lot more than what you’ve paid for. 

Bottom Line

If you want easy storage, easy loading, and superior reliability in a magazine, then you should give the Sig Sauer P365 Micro Compact 9mm magazine a try. Affordable, high in quality, and excellent in performance, this checks off all three boxes without breaking the bank. It’s that holy trinity that most shooters don’t know about, until now. 

Best SIG P365 12-Round Magazine:
SIG Sauer P365 Micro Compact Extended12-Rd Magazine


  • Easy to load
  • Easy to store in tactical belts
  • Excellent grip on the protrusion
  • Cleaning and maintenance is simple
  • Most people were happy with the additional length


  • A few say it’s a bit pricey

What Recent Buyers Report

New users say that they managed to keep this magazine nice and well-functioned after firing over 1000 rounds or more. They said that loading it didn’t take a long time while it was also able to prevent itself from getting beat up or damaged after hitting the hard surface several times. One user said that he was quite surprised by how it could still work despite accidentally dropping it on the floor. 

Why it Stands Out to Us

This magazine will give you a couple of extra rounds compared to some average P365 magazines. You can still be able to use them (and wisely depending on the situation). If you are in a target shooting application, you will probably need extras. But in a concealed carry application, a few might be sufficient depending on how many assailants you are facing. No matter what, you are prepared to survive what might seem like a life-threatening event or are prepped for a good day at the range. 

Who Will Use This Most

This will be great for those looking for a multi-purpose magazine that can do it all. You might not use all 12 rounds or you might. Either way, you’ll go through many shots without a single instance of jamming or malfunctioning. So, you have the reliability factor down in a magazine like this. 

Bottom Line

If 12 rounds are what you want, you’ll get it in the Sig Sauer P365 Compact Extended 12-Round Magazine. You will appreciate the extra two rounds that might come quite in handy depending on the application. Regardless, you have something that will work hard to keep you ahead of the curve against assailants or the time clock if you are practicing for an upcoming competition. 

Best SIG P365 15-Round Magazine:
SIG Sauer P365 9mm 15-Round Magazine


  • Long-lasting quality
  • Fits most P365 pistols
  • Great for multiple purposes
  • Fitting for most hand sizes
  • Easy to insert and remove
  • Super durable construction
  • Provides a great amount of firepower
  • Easy cleaning and maintenance
  • Perfect for concealed carry and target shooting
  • No jamming or malfunctions


  • None

What Recent Buyers Report

Most new users were able to use this for almost any given application where a P365 was warranted. No matter what they used it for, they agreed on one thing: this is a reliable magazine that really comes through in the clutch. One user said that no matter how many rounds he has in the magazine itself, he knows that he will have a plenty of them handy in the event that he needs to defend himself. 

A lot of new users say that this magazine was perfect. They said that with 15 rounds, it was plenty for them to put the bullets to paper whenever they were at the range. One user even said that he uses this for target shooting and competitions because he knows that 15 is enough for him to get an edge on the competition. Plus, he doesn’t have to change out magazines very often due to low capacity.

Why it Stands Out to Us

This magazine has the ability to handle 15 rounds when fully loaded. What makes it even better is that the inner workings have the quality to handle consistently full loads. If you want something that will be high enough in quality to handle the cycle of loading and reloading to near capacity, this is the magazine that can do just that. 

It has an extender that allows you to add more shots to the magazine itself. So, you will be working with a little bit extra and will have a magazine that lasts longer and gives you a little boost in firing power. Plus, this can handle a good quantity of 9mm rounds, so if you have different kinds of 9mm rounds laying around you can put them to good use with this magazine.

Who Will Use This Most

Whether you are a civilian or in law enforcement, there is no such thing as having too many shots to work with. This magazine has the quality and the reliability to provide a strong enough case for you to purchase extras. Don’t be shocked if these wind up being the best magazines you’ve invested in because of their quality and functionality alone. 

If you’re looking for a Sig P365 magazine that will be perfect for all of your target shooting needs, then you’d be hard-pressed to find anything like the Sig Sauer P365 9mm magazine. If you want more shots and better quality in a magazine, this could be right up your alley.

Bottom Line

If you want a magazine that is the real McCoy when it comes to using it for multiple purposes, the Sig Sauer P365 9mm 15-round magazine will definitely deliver on the promise. With so many shots available to you, why on earth would you want to settle for less? 

The Sig Sauer P365 9mm 15-Round Magazine deserves its place on our list because it is proven to be reliable, durable, and able to serve a purpose in so many ways. You’ll definitely want to get your hands on more of these magazines once you try it out and end up amazed by how it functions.
