Can Any Holster Be Used For Concealed Carry?

Just about, yes. In fact, they are required to be worn for the purpose of concealed carry. With that said, while any holster can be used for such a purpose, not all are created equal. Holsters are made in different designs (IWB, OWB, shoulder, ankle, etc) and are also made from different materials. Some of them will be made from materials like Kydex while others are made from leather or nylon, to name a few.

What to Look For in a Holster For Your FNX 45 Tactical

Not every new holster that is on the market is worth spending your hard-earned cash on. Despite the seemingly infinite number of old and new style holsters out there, focus on buying only those holsters that are worth it. The following factors will help you make your choice:

Price vs Quality

Every holster you buy is a compromise between price and quality. While in general, the adage “you get what you pay for” holds true, you don’t always need to spend an arm and a leg to get a holster that gets the job done well.

The right holster will exhibit quality materials, quality craftsmanship, strong construction, and durability. It will also perform well under most field conditions, no matter how roughly you use it. It should be simple enough to work without complications.


A common concern among law enforcement personnel as well as most concealed carry owners is the retention of the holster. While you want to prevent your opponents from snatching the gun from your holster or it accidentally falling out, you also want to be able to draw it fast enough to eliminate threats.

Companies offer various retention levels such as level 1, level 2, etc., but we recommend going with level 1, as it keeps your gun moderately secure while giving you speedy access to your gun.

Comfort and Adjustability

You will typically be carrying your holster and gun on your person for several hours a day, possibly even longer if you’re on duty, so keep the comfort factor in mind. Select holsters whose carrying angle can be adjusted, that won’t press against your body or chafe.  

Things to Avoid When Looking For a FNX 45 Tactical Holster

Poor Fit

The Holster must not just fit your FNX 45 Tactical, it should also fit your body comfortably. It needs to stay in one place as you move around, and not get in your way. So be careful not to select an ill-fitting holster.

Wrong Tension

The tension of a holster relates to retention, as it affects how quickly you can draw the pistol. If the tension is too tight, the holster will not release the gun easily; on the other hand, if it’s too loose, you will constantly be worrying about the gun falling out.  Avoid a holster that has the wrong tension level.

Poor Concealment

In case you want to use your FNX 45 for concealed carry, keep in mind that it is a large gun and hence the holster will be correspondingly big. Not every holster for this gun is suited for concealment, so keep that in mind.

Best FNX 45 Tactical Kydex Holster:
Black Carbon Fiber Kydex OWB Holster

Black Carbon Fiber Kydex OWB Holsters More Than 200 Different Handguns. Left & Right Versions Plus Speed Clips Available.


  • Comfortable
  • Good retention
  • Made in the USA
  • Fits the gun perfectly


  • Belt clips don’t work for every belt size, but you can switch the clips out with standard ones

What Recent Buyers Report 

Most new buyers had no problem with this holster holding their FNX 45 pistols intact. They were happy with the fact that it not only fit their pistols like a glove, but was also very comfortable to wear. One user said that he was able to attach this to his tactical belt and noticed that it didn’t slip out of place or move around. He also added that the quickdraw was a huge possibility since it wasn’t made from materials that allowed for snagging. 

Why it Stands Out to Us 

This holster is made from high-quality carbon fiber, which is perhaps one of the toughest and most durable materials out there. So if you want something that will be excellent in terms of toughness, then you may want to end the search here. Once you strap this onto your belt or waistband, you’ll have a pistol that will be reliable and allow for easy concealed carry. You’ll be well-prepared for any danger that may come your way. If preparedness is important, you should consider getting a holster that will keep you ahead of the curve against assailants. 

This OWB (over the waistband) holster is made from Kydex in a black carbon fiber finish. The holster is custom made in the USA for each handgun model. It comes with a 1-year replacement warranty. It fits close to the body and is easy to conceal with the right clothing. The holster securely holds the FNX 45 Tactical and has good retention.

Who Will Use This Most 

This would be excellent for those that are looking for an OWB holster that will provide the best in quality and has the potential to last you years (or even decades). It takes a tough holster to provide excellent concealability, and this holster might just blow the doors off of any other holster of its class. Believe us, it’s a holster that might generate some envy from your fellow concealed-carry enthusiasts. 

Bottom Line

The Black Carbon Fiber Kydex OWB Holster from Outlaw Holsters might just be one of the most popular holsters on the market for an FNX 45. Simply put, this can probably outpace many OWB holsters by a mile in terms of durability and longevity. That alone equals devoted reliability for a pistol built for self-defense. Attach this onto your belt or waistband and you’ll be good to go. 

This is a great holster for concealed carry of your FNX 45 Tactical, especially if you wear appropriate clothing for concealing the waist holster. With adequate retention and comfortable fit, this holster has a smooth draw and gives you quick access to your gun.

Best Holster for FNX 45 Tactical With RMR And Light: 
Neptune Concealment Kydex Gun Holster for FNX 45

Neptune Concealment Kydex Gun Holster for FN FNX 45 Full Size - Light / Laser Bearing Nestor Series - Veteran Made USA


  • Solid retention
  • Fits the gun perfectly
  • Excellent customer service
  • Made in the USA by veterans


  • Some owners complain of overly hard retention

What Recent Buyers Report 

Many new users were looking for an FNX holster that looked good and had the ability to hold a pistol well with no slippage allowed. Sure enough, there was no disappointment from the new users of this holster in particular. It easily attached to waistbands fairly quickly and never slipped out of place once according to one such user. He also said that he was thrilled with the Kydex material since he had heard so much about it in the past. 

Why it Stands Out to Us 

Kydex has rapidly grown in popularity in the past few years. If you want something that stands as one of the biggest challengers to nylon or even polymer, it’s Kydex that might be the toughest yet. It’s super durable and won’t allow for any wearing, tearing, or any kind of snagging. So if you need a holster that will make quick drawing a reality, then you’re really going to love how this will work to your advantage. Furthermore, it has a locking mechanism that you can put in place so you won’t have to worry about the pistol slipping out at all. Simply put, it’s a holster that is built for the long term and will give you reliable service for as long as you need it. 

This Kydex holster is handmade by veterans in the USA. Nestor Series. The holster can be made for inside or outside the waistband. When ordering, you can specify which light/laser you wish to use with your gun from the drop-down list, and the holster will be molded accordingly. If requested, the order will include MOLLE clips as well.

The tensioner screw allows the user to tighten or loosen the fit of the firearm, which is a must for people who have seasonal weather. In high temperatures the kydex will flex more and loosen a bit, while contracting in the cold weather, hence becoming more restrictive and tight.

Who Will Use This Most 

This would be an excellent holster for the summer months if you are looking to put away the shoulder holster. And it’s definitely the holster for those who are looking for the “last holster they need for a long time”. With the amount of durability this holster has, you probably won’t be surprised if you end up using this in the next year and the year after that. 

Bottom Line

If you want superior durability in a holster, the Neptune Concealment Kydex Gun Holster will be the best possible choice for you. Yes, you love your FNX 45. But do you love it enough to take good care of it? Will you be prepared for what might happen when danger is lurking around the corner? If you answered yes to these questions, you deserve a pistol that will never disappoint. 

It is a good holster for any FNX 45 Tactical, but features exceptional purchase value if you have flashlight or laser attachments on your firearm. The fit and finish are excellent, so you are sure to be happy with the holster’s quality.

Best FNX 45 Tactical Shoulder Holster:
King Holster Tactical Shoulder Holster For FNX

KING HOLSTER Tactical Shoulder Holster fits FN 509 | FNS | FNX | FN Five-Seven


  • Comfortable
  • Works for multiple guns
  • Adjustable for different body sizes


  • Free to move under clothing, but not so good for concealment
  • Magazine pouch is not suitable for left-hand draws due to orientation

What Recent Buyers Report 

Many new buyers were able to put this holster to the test in colder temperatures while they were working in professional security. Either way, they were ecstatic about how well this holster kept their FNX 45 pistols concealed for the long-term. No-bulge, no-slip, no problem, according to one user. He said that he was able to strap this on his shoulders and with some mini adjustments it was able to fit his frame perfectly. 

Why it Stands Out to Us 

This holster is no OWB or IWB design (obviously). It’s a holster that might be required for some professions, and one of the reasons for that is discreet carrying. Think about it: you are carrying a pistol. Nine times out of ten, a potential assailant may be looking to see what kind of a threat you might be just by making sure you’re not carrying a pistol. But won’t that poor unfortunate soul get a stunning surprise once you are able to use it to warn them off or open fire if needed in a time of grave danger. If you want a holster that will really catch an attacker by surprise, this could very well be the one you’ll go for. 

This universal shoulder holster is reversible for right or left-hand cross draw and can fit most large and medium frame pistols, and a double magazine pouch. It is fully adjustable to fit small or large body frames and is well built and comfortable compared to similarly priced holsters.

Who Will Use This Most 

This will definitely be a great holster for those in professional security, law enforcement, or those who simply carry for the purpose of everyday use (while keeping the pistol warm during the winter). You may want to give this the old college try if you’re kind of getting a bit tired of the whole OWB or IWB holsters. We wouldn’t blame you if you do. 

Bottom Line

The King Holster Tactical Shoulder Holster for FNX is the go-to option for many concealed carry users who like to keep it discreet. You’ll be able to strap this onto your frame and be able to carry your pistol every day so you are ready to take on danger head-on. And by the way, it’s pretty affordable as well. So you are getting excellent durability and maximum concealability (among other perks) for a steal of a price. 

While this is a good shoulder holster, it doesn’t offer the same level of concealment or retention as compared to many OWB and IWB options out there. Purchase this holster if you want to carry your FNX 45 in a shoulder holster option comfortably and if you are not too concerned about concealment.

  • Solid rivets
  • Thick Kydex
  • Good belt clip
  • Strong retention


  • Kydex mold they use can interfere with the external safety
  • There is no retention adjustment; the kydex is hard riveted in-place
  • Leather backing is not lined, and the hardware comes into contact with your skin

What Recent Buyers Report 

As expected, a lot of new users were pretty happy with this holster in general. The material itself made it really comfortable to wear for most users. And best of all, it caused no skin irritation, even for the most sensitive of skin. One user who reportedly had sensitive skin even said that he was able to wear this holster in the summertime and would not have one single instance of irritation. He said that it was more than enough to keep this holster for the long haul. Overall, the holster held up FNX 45 pistols quite well with no wiggling or slipping to speak of. 

Why it Stands Out to Us 

This holster will provide comfort and maximum concealability like nothing else. So if you are in search of a holster that will deliver on those promises, you certainly won’t be disappointed with this one. Once you clip this onto your belt or waistband, you’ll be able to carry your pistol on an everyday basis without having to worry about it moving around all over the place. Even better, it will remain durable and reliable for a long time thanks to the hybrid mix of leather and Kydex. If you want a really good IWB holster that will put others to shame, you’re going to find this one to be quite hard to resist. 

Our top pick for the best IWB holster for the FNX 45 Tactical is the Nt Hybrid Kydex holster. Made from leather and Kydex, the leather side is worn against the body while the Kydex faces outwards. Each holster is molded for the specific gun model. This holster clips securely onto a 1.5” belt, is made in the USA, and comes with a 1-year replacement warranty.

Who Will Use This Most 

This holster is for those who are in search of maximum concealability and comfort all rolled into one package. For the price it’s going for, why wouldn’t you want it in your collection of holsters? If you want your concealed carry holster to be superior in strength and reliability without creating any unsightly bulges or drawing undue attention, this holster will certainly stand out as one of your best choices yet. 

Bottom Line

The NT Hybrid is an IWB holster that might be one of the best kept secrets among concealed carry users. And it will make your firearm a best kept secret when it comes to concealability as well. Wear this like a pro and you’ll not only be prepared for anything that may warrant you to use your pistol but you’ll also be able to wear this without any discomfort or worries about the pistol slipping out.

Perks of Getting a New FNX 45 Tactical Holster

Investing in a new FNX 45 tactical holster is certainly worth every penny, especially when you are able to get used to the holster as you break it in.

Provides Excellent Concealability

Superior Quality

All of these FNX 45 holsters are made from high-quality materials. So these will last you a long time and will be able to hold your pistols in place with no wiggle room or any chance of slipping out. Also, the better quality the holster, the better the chance it will last you a long time. Remember, holsters made from certain materials will be better than others, so keep your eyes peeled for the best durability you can find. 

Unmatched Reliability

Reliability and the ability to hold your pistol in place will be important. Once again, this ties into superior quality. A great quality holster will do wonders for the overall reliability of a holster. So if you want a reliable holster, this is your friendly reminder once again that high-quality materials matter most.
