Duration: 9:10

The Glock 21SF Gen 3 is a substantial .45 ACP pistol, offering a 14-round capacity and a low bore axis for manageable recoil. While reliable over 4,000 rounds (except with Tula steel-cased ammo), its 'chunky' grip remains a challenge for smaller hands. Modifications like grip tape and Ameriglo sights improve handling and durability over stock plastic sights.

The Glock 21SF Gen 3 is a .45 ACP pistol with a 14-round capacity. It features a low bore axis for manageable recoil and a 'Short Frame' (SF) grip. Common upgrades include grip tape and aftermarket sights due to potential durability issues with factory plastic sights.
