Modular. Flexible. Concealable. Comfortable. Optic compatible. This is the Sidecar Holster.
The T.REX ARMS Sidecar Holster is the industry-standard solution for effective and comfortable appendix inside-the-waistband concealed carry. Our modular attachments allow you to carry things like an extra pistol mag or tourniquet alongside your firearm. The T.REX Spine System allows you to easily swap out attachments and flexes as you move to conform better to your body. This provides increased comfort and concealability, while also retaining the stability you need for maximum consistency when you draw your pistol or grab your magazine for a reload.
If you want to run your holster without an attachment (in the appendix or 3-5 o'clock position), each holster comes with our Sidecar Wing, which has a stabilizing belt clip and mounting holes that can be used to attach knife sheaths or other tool holders so you can easily assemble your own attachments. This is the most adaptable holster system on the market, and more attachments are in development.

I love the design of the holster and the build quality. It doesn't feel cheap or half put together . Definitely the same quality we've come to expect . But like most holster its not fat guy friendly. I know this is a me issue, but the industry does need to stop treating every gun carrier like we are all skinny

I wear my sidecar holster all day, everyday and have had it for quite a while now. I believe I purchased it in 2023 and it developed small crack because I work manual labor and it takes a beating. These guys replaced it no questions asked. I had a new holster the same week I placed my inquiry which is far more than I was hoping for. This company stood by me and its product, and in doing so earned a customer for life. We need more business like this.

I love how simple this holster is! None of this unnecessary material (bungee cord crap, etc). Even for bulkier firearms it is pretty slim fitting and super easy to conceal. The simplicity is what keeps me using this holster. As a LEO who carries everyday (in LV) it is comfortable, even during the summertime. I also like the fact that you can use other attachments, but personally I just run the extra mag. Simple holster with great retention that gets the job done!

Perfect fit and function for the everyday carry or competition. First fit quality with no tweeking or modifying. And it carried over to left-hand option.

The holster is fantastic. I have 5 of them and love them. Get a Sidecar second-hand. Don't order anything from TRex. They sold their founder under the bus, and the company is run by egotistical maniacs now.

Extremely comfortable and fast holster! While they’re extremely well made, they have the best warranty out there! I’m hard on my gear and T~Rex ALWAYS replaces my holster without question! The other plus new customers don’t realize, is warranty replacements come before new sales so you’re never without your holster for too long!! You won’t be disappointed!!

The retention with a TLR-7 Sub isn't very good, despite a lot of futzing with the adjustment points. It's frankly a bit of a disappointment in terms of comfort and fit for the price and I'm currently trying to get rid of it. I don't doubt the quality/durability of the materials, but the fitment and comfort is the deal-breaker. Maybe this is an issue inherent to the TLR-7 Sub, as I've had another bad holster from another company, but I would probably not recommend this product.

So the quality is top notch materials feel solid. The holster holds the gun and your mag very well. I will say it was very hard to get this to ride comfortably. The wing to set the gun back into you is way oversized and I ended up taking it off. I wish I came with a smaller one but it doesn’t so I just run it without the wing because that’s the most comfortable way I found. Missing the piece I won’t lie the gun feels like it falls forward but at least I can wear it. It may work better with a floppy belt I haven’t tried I do know with a stiff belt it’s kind of hard to make it work well.

I carry it 14-16 hours a day, it is by far the most comfortable way to carry AND conceal a glock 19 and spare mag. I have carried a sidecar for 9.5 years 7 days a week, and my experience shows that. I am currently using sidecar #19. Having broken 18 of them I will say that the customer service is top notch. They have made me several custom holsters trying to make them more durable.

This is my 3rd time purchasing one of these, despite the YouTube drama and politics aside, this is the best iwb holster to date.

This Holster actually works very well and holds my gun good on my belt with the metal clips. The sidecar Mag attachment was also really good, it evened out the weight of my gun and holds even better with it on. I will say the comfort of the holster is a little off and rubs against you a little. T-rex arms needs to make the sidecar holster have a little pad on the back.

I love this holster,. My only issue is the same issue I have with all holsters this shape and size. Too wide to sit on one side of the belt buckle while not being wide enough to clear the belt buckle comfortably. Quick fix. Put the buckle on one side or the other lol

I really like the fit, I’m a full size guy so I carry full size guns, and it conceals my full size Walther PDP with a WML and an Acro really well. I do wish the bottom corners were a little more rounded as they can be a little sharp.

This was the only option for my setup and everything f9its perfectly. Very happy

There is a reason why I’ve got one for each one of my firearms that I carry regularly. A great product that fits well easy to conceal and easy to draw from. The retention is solid and overall looks good. It’s comfortable it fits the firearm and the durability is exceptional.
