Safety First

We believe that the TACRIG holster system is the safest option on the market. With our unique multi-platform shells you can safely move your firearm with you wherever you go.

Your firearm and shell moving with you means that you can eliminate the need to draw and re-holster. Most holster-related accidents happen during drawing and re-holstering the firearm. This will also prevent unnecessary wear on your firearms over time.

Our Boltaron shells restrict any access to the trigger while your firearm is holstered.

There is a noticeable difference in the way we approached the hybrid type holster. We added a second layer of material to the back of our shell so the the trigger cannot be manipulated even if the backer is forced away from the firearm frame. We accomplished this while only adding .06 of an inch to the total thickness of the holster. Traditional hybrid holsters fail to block access to the trigger from the back of the holster.

Modular Shells

Multi platform: IWB (in waistband), OWB (outside waistband)

Drop Leg, Chest, AIWB (appendix inside waistband) coming soon.

We only use the best materials. We decided to use Boltaron instead of other plastic sheet materials. Boltaron is a company based in the United States that makes mil spec plastic sheets that are able to stand up to much higher and lower temperatures without deforming and losing its molded characteristics.

Get a grip! TACRIG holsters provide the user with full access to the grip of his firearm. Believe it or not, there are holsters out there that do not offer this basic feature.

We believe retention is a crucial part of a good holster. TACRIG holsters undergo an extensive precision retention engineering process that is accurate down to the thousandth of an inch. Every firearm is 3D scanned and designed into our own unique molds that we make in house. We do not use the same gun molds everyone else has. We found those to be an inaccurate comparison of real world firearms. We believe “adjustable retention” is sometimes used as a way to make sloppy holsters that can later be adjusted to fit the firearm the right way.

All our shells are compatible with threaded barrels, suppressor height sights, and optics. There’s no need to buy another holster when you make upgrades to your firearm. At a later date, we will offer shells that are compatible with various lights and lasers. Stay tuned!

Our holster shells have about a 3mm flare on top to help you re-holster. When practicing your quick draw, you will appreciate that we have added a safer and easier way to get the firearm re-holstered.

Breathable Backer

Our in-house engineered breathable sweat shield is at the core of the TACRIG holster system. We engineered this holster to be compatible with EVERY semi-automatic firearm on the market.

Our backer material blend is stronger and more durable. There’s no need to break it in, and it will not smell like leather backers do.

TACRIG backers fully adjustable cant 15° in either direction.

Premium Hardware

We searched for a very long time to find the right hardware to accompany such an incredible holster system. The TACRIG hardware is extremely strong offering over 1,000 pounds of vertical and horizontal breaking strength. It is made of coated brass meaning it will never rust, even on the hottest days.

Our backers also feature tuck-able belt clips. You can carry concealed IWB and tucks in your shirt. Nobody will ever know.

We will be adding many accessories in the coming months. Some of which include: **There is not a listing.

We have also partnered with Ulticlip and will be selling their clips as an optional upgrade to the TACRIG holster packages.

    The holster fits my Glock 43x MOS perfectly. My firearm sits in place and the holster passes the upside down test and the firearm doesn’t fall out. I love that it has a slide cutout for my Holosun 507k. The holster itself is very comfortable and I am a bigger guy so this style of holster just works. I did a special order and ordered the holster in OD Green and it looks awesome. After speaking with the owner on Facebook it is clear that he cares about his customers and his business by going above and beyond with what you need. He spent his weekend getting my order ready when he could of waited for Monday to roll around. Can’t beat that kind of customer service! Thank you again!

    Very versatile holster system. I carry the p366 as well as own a p320. One of the main reasons I selected this firearm is the modularity that they allow. Tacrig takes that same modularity and applies it to holsters. Their system is very intuitive and also very secure. Don’t get me wrong the price is up there, but I do genuinely believe you get what you pay for and this will last forever. I was also blown away by how comfortable the setup is. The rubber backer is durable so it won’t be dented or create wear, but also is very comfortable as a padding. Very impressed and look forward to all the quick attach systems coming in the future. A person request would be to create a car mount system.

    Very happy with my purchase.

    I carry a full size Gen4 G21 so anything smaller than a large button up shirt prints but that’s expected with a sidearm of this size… 3:00 position is best for me… The one hand draw from this holster is really good, with a fitment that is snug but not so snug to where you’re struggling to pull… The trigger guard is well protected and covered enough to keep debris / objects out of the dangerous areas, but there’s plenty of room for a positive pull, placing the trigger finger in the perfect spot along the slide for proper trigger safety… The part of the holster that makes contact with the body is very comfortable and light, obvious breathe ability and does not have scratchy hardware causing someone to fuss with it blowing their cover…!!! Also the belt loop hooks are very sufficient in keeping the holster in place when drawing, and keep the sidearm nice and close to the body, creating a very slim profile… I highly recommend this holster if you’re running a full size carry, and having a modular design is an added bonus for running any of my other carry pistols…!!!

    I was completely impressed with this product starting with the packaging. The holster and its componets are of very high quality, amazing comfortability. I purchased this for my Legion P226 SAO so I need a holster that had the ability to handle a heavier weapon. I will be buying more shells so that I can rotate out from time to time.

    Man, this thing is comfortable.

    As soon as I got this holster out of the bag I instantly saw the quality and craftsmanship difference right away. Compared to many IWB holsters that I’ve tried this holster is definitely on top.

    Customer service is top notch. Tim Silva you rock dude

    If you’re on the fence or unsure about their holster, order it. It conceals an xds and a hellcat rdp very well. Its more comfortable than my crossbreed and the backing doesn’t get hot like leather does. I wish I would have taken a chance on this sooner rather than wasting money on holsters.

  7. Dale (verified owner)

    Perfection. I purchased the holster for my P365X with Icarus EVO grip. The fit is perfect, comfortable and adjustable. I was able to quickly raise one of the clips higher to achieve a nice can’t for my 2:30 draw. Excellent product. I also appreciate the packaging.

    I would have loved to give this holster 5 stars, but the cant adjustment is too limited. I prefer a fairly high cant angle, but in order to get that, I had to move the belt clips as far as I could toward the shell, as well as to the extremes vertically, sacrificing most of the flexibility of the backing. I do like the stiffness of the shell to resist compression when unholstered, making reholstering easy. It also fits my EDC with mounted light like a glove.

      Hi there, we have other belt clips that we can send out that will allow a much more extreme cant angle. Let us know if you’d like to try those out. 🙂

    So my Tacrig holster came in today, and all I have to say is WOW! The build quality is by far more superior than any of my other holsters for my other pistols and nothing compares to how comfortable this set up is, even with the full size of the Echelon. I can’t wait to add more for my other carry pistols.

    Got the FLEX IWB package for my psa dagger compact x and holosun PID. This holster is so comfortable and I forgot I even had it on. I don’t have any of the other accesories tacrig offers just yet but removing the holster shell from the flex iwb piece is extremely easy and super solid. Highly recommend this holster to anyone who carries on a daily basis. I carry for 10-16 hours a day sometimes and comfort, strength, and weight matter. And this holster has it all. BUY IT.
