Built on Glock’s Short Frame architecture, the SF grip reduces trigger reach while maintaining the 13-round capacity that sets the Model 21 apart from most .45 ACP pistols. Finger grooves and a standard Glock accessory rail provide secure handling and easy mounting of lights or lasers.
The 4.61-inch steel barrel uses Glock’s polygonal rifling for reliable accuracy and long service life. Coupled with the Safe Action striker-fired system and a 5.5-pound connector, the trigger break is consistent from the first shot to the last.
A Tenifer-treated matte nitride slide resists corrosion and wear, and rear serrations offer positive grip during press checks and manipulations. Fixed polymer sights with a white-dot front and white-outline rear deliver a clear sight picture out of the box.
This Gen 3 variant remains on the California Handgun Roster, making it a straightforward choice for buyers in restrictive jurisdictions. The SF configuration was originally developed for the USSOCOM Joint Combat Pistol trials, adding a layer of military pedigree to the platform.
