Product Information & Specs

Eight years after Glocks original unveiling of the G21 the G21 Gen 3 was introduced. Chambered in 45 ACP with a polymer frame and a 10 plus 1 capacity in a staggered-column magazine the Glock 21 Gen 3 is a semi-automatic handgun manufactured primarily for the American market. It featured a built-in accessory rail known as the Universal Glock rail thumb rests on both sides of the frame and finger grooves on the front of the grip which also had checkering on the front- and backstraps along with textured sides. Later versions of the G21 Gen 3 also featured a modified extractor that doubled as a loaded chamber indicator an enlarged locking block and an extra ross pin.


Remarkable for its accuracy and light recoil the GLOCK 21SF delivers the legendary stopping power of the .45 AUTO round with 10 plus one round magazine capacity. Countless law enforcement units swear by the G21SF pistol and thats why this powerful lightweight all climate workhorse is standard issue from the North to South Poles. The SF model reduces the circumference of the receiver at the rear or back strap offering increased comfort and control-especially for shooters with smaller hands. - 45 AUTO Safe Action - Length 8.03 in. - 1.27 in. - Length Between Sights 6.77 in. - 5.47 in. - Barrel Height 1.26 in. - 4.60 in. - Weights Unloaded 29.30 oz.

Many online gun sales actually take away from your local community.  Instead of buying a gun that’s on your local store’s shelf, most retailers drop ship it from a warehouse in another state.  At, if an FFL is part of our network, we sell THEIR guns first whenever possible.  That way, we’re helping small businesses in your community AND if they have it in stock, you can pick your gun up IMMEDIATELY – it’s how business should be done.


Most everything can be easily bought online these days.  But for some reason, buying a gun online can be complicated.  Most websites are poorly organized, don’t tell you a lot about what you’re buying, and leave you on your own to figure out what you want. is built to be simple – easily organized products, useful descriptions from experts, and support to guide you to the right choice.  Spend your time enjoying the gun you want, not getting frustrated with a complex website that makes gun buying hard.
