USED - Will Show Cosmetic Wear

As with many used and police trade-in firearms, these may contain light scratches and/or holster wear. This is not always the case but should not be unexpected. These pistol will show cosmetic wear, but most wear will be isolated to one or two spots. Pistols still function and were tested by an armorer before traded in.


Fully tested and operational Gen 3 Glock G21

Glock G21 SF Gen 3 for sale online with free shipping included at We, Target Sports USA offer the best selection of Glock semi-automatic handguns for sale online, including this like new, police trade in G21 Glock 45 ACP Gen 3 handgun. 

Glock G21SF features an extended barrel and an extended line of sight, which in turns offers greater accuracy even with rapid fire use. In addition to the extended barrel, the Glock G21SF comes with 2 additional 13+1 round magazines ( 3 total mags). 

Remarkable for its accuracy and light recoil, the GLOCK 21SF delivers the legendary stopping power of the .45 AUTO round with 10/13 round magazine capacity. Countless law enforcement units swear by the G21SF pistol, and that's 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.

The Glock 21SF was originally developed and designed to compete in the currently cancelled US Military Trials that were seeking a .45 ACP pistol to replace the current Beretta M9. The first Glock 21SF's developed and designed for the military included popular revisions such as the picatinny rail system (which replaces the common 1913 rail system on most other Glock pistols) and the ambidextrous magazine release, along with the well designed frame reduction designed to ensure that the grip is more universal. The Glock 21 grip reduction extracted material mainly from the backstrap of the grip.

Comments and Reviews on Glock G21 Short Frame Gen 3 USED Handgun 45 ACP Auto 13+1 Rounds *Police Trade In
Holster worn through to the metal and scratched up. Grip worn slick by right handed officer. However, it shot everything from 135 gr Honey Badger to 230 plus p without a single FTF or FTE. Called Glock and found out this gun is 9.3 years old, and the favtory Glock night sights are still working, and the firearm seems cited in. If you can stand a holster bare metal slide, slick grip, and some scratches, these are a terrific deal IMHO.
