The T.REX Ironside is an OWB (outside-the-waistband) concealment holster with adjustable passive retention, specifically designed to fit comfortably on your waist in the 3-5 o'clock position. The Ironside is ideal for people wanting to carry concealed under a jacket or button-up, or for people who don’t prefer carrying inside the waistband. It features 1.5" or 1.75" belt loops, which are adjustable so you can set the angle (cant) of your handgun, from -5 to +10 degrees, to ensure a solid, intuitive grip when drawing. It's made of durable, precision-formed .093" Kydex and comes in light-compatible and non-light-compatible models.

I’ve purchased three of these holsters and they’re great. They sit nice and tight on your hip and conceal very well with normal fitting clothes during any season. I’ve recommended this to friends who were skeptical about an OWB holster and they love it. You won’t be disappointed.

Nice tight fit for best OWB concealment, even with a light! The Ironside & T-shirt cover is all I need. I think it is the belt loops they make and how they are attached directly to the holster. Fit is perfect.

The holster is lightweight and feels solid but pistol does not click into it, like most kydex models.

Holster is comfortable and rides well on belt. Great retention as well. The color I ordered came in looking drastically different than I thought it would when I ordered, T. rex swapped it out no questions asked!!!

I bought this cause tennicor doesnt make an owb for G34. I thought it would not compare to the tennicor one piece design but it has. No loose screws nor belt loops. It doesn't seem super sturdy at a glance but i have been pleasantly surprised. It has been my edc for all of 2026. Good product.
I purchased a Ironside Holster for my Glock 45 Gen 6 COA . The holster shipped fast but I noticed that the screws seemed to be short and when adjecting retention the belt clip had lots of play. ( see photos ) TREX sent a holster parts kit but did not include any longer screws. The holster is a budget option so I guess it's t be expected and the Kydex is is already wearing on the slide on both my Gen6 G45 and Gen3 G19. You get what you pay for I guess.

I have several of these OWB holsters utilized for some of my full size pistols and have been very happy with fit & finish of the holster for a reasonable price. Only 4 stars because i have broken 2 separate belt loops and have had to order a spare set with each holster order. Would like to have a more robust set of belt loops, especially for heavier full size pistols.

The finish on the outside is really nice. The camouflage looks great. The inside seems to me like they were working with a mold that has been beat to crap and time to retire. It was not smooth, rather lumpy, and the components of my Surefire X300U were rubbing the inside so bad that it was leaving kydex particles in places that were not formed correctly. Like I mentioned, the mold they used to make the holster may have been used 75 too many times. I adjusted the holster many times to try to make it fit. After all, this is probably my 20th kydex or Boltaron holster, so I'm experienced with how they are supposed to fit. After a little Dremeling, trimming, and filing, it works like it should have out of the box.

Fits like a glove. Great quality.

I like how easy I can still conceal carry with this holster it’ll be easier with a jacket or coat but here in South Fl I’d lean towards the raptor holster

The comfort and concealment of this holster are fantastic. The materials used are superior. I’d prefer the option for a more negative cant, but it works. Great holster for daily concealed carry. I don’t know why the g43xmos has to use the g48 cut. It’s a little long, but it functions.

Quality is top tier, perfect fit, and customer service is top notch.

The holster is okay. It doesn’t fit around the buckle of my tackle belt. It is super tight around my Sig. very hard to get out of holster.

I’ve gotten a few holsters over the years, always solid quality, and the little improvements that make a noticeable difference are very much appreciated. For example, changing some of nuts and bolts, literally, that makes it much easier to make adjustments to positioning. 10 out of 10 Would recommend 👍
