Glock 21 SF .45 ACP 4.6 Barrel 13-Rounds Used

Overview

Glock 21 SF Used Features The Glock 21 SF is built around a 4.6-inch rifled carbon steel barrel chambered in .45 ACP with a 1:15.75-inch twist rate that provides consistent stabilization across the wide range of .45 ACP projectile weights and load types that the platform is commonly used with from standard 230 gr ball ammunition to defensive hollow point loads and reduced recoil training rounds. The striker-fired Safe Action system eliminates the need for external hammer management or manual safety engagement delivering a consistent trigger pull of 5.50 lbs. average that is the same from the first shot to the last and supports fast reliable fire under the stress conditions that defensive and duty applications demand. For duty professionals law enforcement officers and serious defensive handgun users who want a full-size .45 ACP pistol with a reduced-circumference grip frame that fits a wider range of shooters without grip reduction gunsmithing the 21 SF delivers the platform capability the application demands. The short-frame designation reflects the reduced grip circumference that Glock engineered into the 21 SF specifically to address the grip size concerns that some shooters had with the original Glock 21 making the 21 SF accessible to shooters with medium and smaller hand sizes who found the standard frame difficult to manage comfortably across extended range sessions. The polymer frame keeps overall weight manageable for a full-size .45 ACP platform while providing the impact resistance and dimensional stability that Glock polymer frames are known for across decades of duty and field use worldwide. The equipment rail provides a standardized attachment point for weapon lights and lasers supporting the configuration of the 21 SF as a complete home defense or duty pistol without requiring aftermarket rail adapters. White dot front and white outline rear sights provide a fast high-contrast aiming picture that supports rapid target acquisition in a wide range of lighting conditions and the matte black slide finish reduces light reflection that could compromise the shooter s low-light operational effectiveness. For home defense users range shooters and serious .45 ACP handgun buyers who want proven Glock reliability and the short-frame grip advantage in a used platform at an accessible price point the Glock 21 SF is available for sale at GrabAGun.
