Holsters for Glock - 21SF


Glock 21SF Holster by Alien Gear Holsters

The Glock 21 speaks for itself as a sidearm, but some prefer the Glock 21SF as it offers greater comfort. Likewise, you should carry in comfort. Alien Gear has a Glock 21SF holster for just this application.

If concealment or inside the waistband carrying is your preference, look at our Cloak Tuck series. Each Glock 21sf Iwb holster features our adjustable shell retention system, and belt clips or loops adjustable for ride height and cant. You can set the draw and carry position, for maximum security and comfort.

The holster base for our original Cloak Tuck is black or tan leather. It’s a classic, time-tested style. However, if you’d like something a little more space age, then check out the 3.0. The Cloak Tuck 3.0 uses a core of spring steel, which needs no breaking in. It’s strong enough to provide a lifetime of service, but flexible enough to wear in perfect comfort. We finish the iwb holster with a neoprene back to repel moisture and the front with our Alien Skin surface, which won’t scuff your firearm while keeping it in place once holstered.

There is also our Cloak Slide, a Glock 21sf OWB holster with the same adjustable shell system as the Cloak Tuck series.

Still not convinced? You can take a 30-day test drive. Purchase is required, but you can return an Alien Gear holster within 30 days of purchase if unsatisfied. We also offer an Iron-Clad guarantee for the lifetime of the holster against defect or damage. You also get a lifetime enrollment in our shell swap program. If you get a new gun, you can exchange your old shells for the new model you’ve bought and still keep the same holster base. Once you buy an Alien Gear holster, you may never need another one.
