Glock 17 OEM Locking Block
The Glock SP00308 Locking Block is a genuine factory OEM replacement part for 2-pin frame Glock 17, 17L, and 34 pistols. Machined from hardened steel to exact factory specs, it secures the barrel into lock-up and controls slide timing during the recoil cycle — a critical wear part on any high-round-count Glock. Installation is straightforward and requires no fitting, dropping directly into the frame with the factory locking block pin. A must-have for armorers, parts kit builders, and shooters maintaining older 2-pin Glock 9mm pistols. Note: this part does not fit 3-pin frames, the G43, or the G42.
