    Glock 21 Holster by Alien Gear Holsters



    There’s a reason why Glock dubs the Glock 21 their workhorse. It’s as reliable as it is tough, and it comes as little surprise that many law enforcement personnel rely so heavily on this firearm. Best of all, this .45 safe action pistol can be concealed. To provide you a quality Glock 21 holster, pair it with an advanced Cloak Tuck 3.0 IWB by Alien Gear Holsters.

    This Glock 21 IWB Holster is nothing short of perfection. With its neoprene backing and flexible design, the Cloak Tuck 3.0 will give you hours of continuous holster comfort, while staying fully concealed. The closed-cell neoprene will mold to your side and will disperse the weight of your Glock 21 across the entire holster base. If you wear this Glock 21 inside the waistband holster at the 3 o’clock position, the ‘wings’ will flex and form to your waistband within seconds.

    To match comfort with sheer strength, our engineers (who conceal carry themselves) have embedded a layer of spring-steel into the core of the Cloak Tuck 3.0. This, along with a thin layer of ballistic nylon, will match this G21 IWB holster’s comfort with superior strength. Durability has never felt this good.

    Customization is also a priority here at Alien Gear Holsters. As a result of innovative gun holster design, you’ll be able to adjust the cant (angle), ride height, and retention with the turn of a few screws. We believe that your Glock 21 should be located in a position that works for you.

    We also embrace the natural quality of fine leathers. That’s why we offer the Cloak Slide a Glock 21 OWB holster, which connects to your gun belt, and our original Cloak Tuck. Both are made with premium drum-dyed leather. The good stuff.

    We back each Alien Gear Holster with a 30-Day Test Drive, free shell trades for life, and a Forever Warranty. Conceal the strength of spring-steel today.
