SCT Manufacturing Full Size Frame Features The SCT Manufacturing Full Size Frame adds an aggressive texture grip a high beaver tail with a low profile bore axis and a flared mag well that speeds up reloads under pressure. Serrations and an index point on the trigger guard help control recoil while a Gen 5 style slide lock and a larger trigger guard give better access to gloved shooters. A Picatinny rail built to MIL-STD 1913 spec rather than a proprietary Glock rail lets the frame accept standard lights and lasers. The grip angle matches factory Glock geometry so the transition for an experienced shooter feels familiar from the first draw. This frame is compatible with compact 9mm 40 S&W and 357 SIG builds giving it genuine multi-caliber versatility on one platform. The assembly includes an electroless nickel locking block a polished trigger assembly with electroless nickel trigger bar a standard slide stop assembly and a polished 5.5 lb electroless nickel trigger connector. Each unit is hand assembled rather than mass produced which is reflected in the fit and function testing every frame undergoes before leaving the shop. For builders who want a reliable serialized foundation compatible with Glock Gen 3 17/22/31 components this frame is ready for a slide right out of the box.
