About Glock 21

Glock Ges.m.b.H., trademarked as Glock is one of the most famous and successful firearm producer, well known all over the world.  Engineer Gaston Glock, company's founder who had no experience with firearms manufacture or design, became one of the most successful firearms designer of all times. Glock had extensive experience in advanced synthetic polymers, knowledge of which was very important in the company's design of the first commercially successful line of polymer frame pistols.

The Glock 21, is very similar in size to previous model, chambered with 10mm ammunition. In fact, the frames appear to be identical. Test specimen of a prototype Glock 21 has an overall length of 8.27 inches and the barrel length about 4.6 inches..  The weight of the Glock 21 unloaded is 29.5 ounces. Almost 85 percent of this mass is accounted by the steel components. As the other models of the Glock series, there are only 35 parts including the magazine. The G21 is a short recoil operated, with the barrel that is locked to the slide by a single lug. During the recoil stroke the barrel moves immediately rearward about 3mm and until the bullet leaves the barrel it pressures drop to a safe level. The barrel on the G 21 then drops downward and separating from the slide and terminating any further motion. The slide is continued rearward movement and counter-recoil cycle are those from the Browning system. It’s a striker-fired, hammerless model with the Glock's trigger and firing pin mechanisms that are quite progressive.

What Makes a Great OWB Glock 21 Holster

A well made, custom  Glock 21 OWB holster will hold your firearm even if it doesn’t come with a safety strap. The glove-like fit and high natural retention are a result of your new Glock 21 holster being molded on the exact replica of your pistol. Thanks to the way your new holster is made, your handgun will not fall out of the holster even if you decide to carry your rig upside down (although we advise you not to carry this way). However, if you want to get as much retention as possible, feel free to choose from our selection of Glock 21 OWB holsters equipped with a thumb-break strap.
On the other hand, a perfect fit isn’t the only thing a great holster should deliver. A great Glock 21 OWB holster should also come with smooth edges and meticulous stitching. Such features help to protect the holster from abrasion, scratches, wear as well as prevent it from taking any damage should it come in contact with rough surfaces. A great Glock 21 OWB holster also comes with a perfect finish, which keeps it protected from dust and moisture. However, in order to ensure longevity and perfect condition of even the best holster, you should regularly take care of your Glock 21 OWB holster through proper holster maintenance.
