SCT Manufacturing Full Size Frame Features The SCT Manufacturing Full Size frame is a serialized shooter-oriented frame built with installed over-molded rails ready to accept Glock Gen 3 17 22 and 31 slide assemblies. Serrations and an index point on the trigger guard help control recoil while matching serrations on top of the beaver tail reduce glare under bright light. A Gen 5 style slide lock with included spring a flared mag well and a thumb accelerator pad round out a feature set aimed at faster more confident handling. The frame carries a Picatinny rail rather than a proprietary Glock rail giving builders a standard MIL-STD 1913 mounting option for lights and lasers. Finished in an OD Green polymer with an aggressive contour grip texture the frame balances a secure hold with a factory-matching Glock grip angle for familiar handling. A high beaver tail combined with a low profile bore axis helps manage muzzle flip and a recessed contoured mag release area speeds up magazine changes under pressure. The frame ships with a locking block already installed saving builders a step and it supports multi-caliber builds in compact 9mm .40 S&W and .357 SIG. For builders assembling a Glock-pattern pistol who want more features than a stock frame the SCT Manufacturing Full Size Frame is a capable budget-friendly foundation.
