SCT Manufacturing Full Size Frame Features The SCT Manufacturing Full Size Frame is a serialized polymer frame compatible with Glock Gen 3 17 22 and 31 slides built with shooter-oriented ergonomics throughout. Serrations and an index point on the trigger guard help control recoil while serrations atop the beavertail reduce glare during aiming. The frame includes a Gen 5 style slide lock flared mag well and a thumb accelerator pad each adding to faster more confident handling. A Picatinny MIL-STD-1913 rail rather than a proprietary Glock rail gives builders broad compatibility with lights and lasers already in their kit. An advanced contour grip with aggressive texturing keeps the frame secure in hand and a high beavertail with a low bore axis keeps muzzle flip manageable during rapid fire. The frame matches factory Glock grip angle so builders familiar with the platform will feel at home immediately. A recessed contoured mag release area speeds up magazine changes and the larger trigger guard improves access for gloved shooters. With the locking block installed and compatibility across 9mm .40 S&W and .357 SIG this frame gives builders a multi-caliber capable foundation ready for a slide assembly right out of the box.
