SCT Manufacturing Full Size Frame Features The SCT Manufacturing Full Size Assembled Frame ships complete with SCT Gen 3 17 compatible internals including a polished trigger assembly with an electroless nickel trigger bar polymer trigger magazine catch and spring and a slide stop assembly ready for installation. Each frame is assembled using parts tested to meet or exceed OEM specifications then function tested with a genuine Glock factory slide to confirm safe operation and consistent trigger reset. Serrations and an index point on the trigger guard aid recoil control while serrations on the beavertail reduce glare. The frame includes a Gen 5 style slide lock flared mag well and thumb accelerator pad for faster more confident handling. An aggressive texture grip and factory-matching grip angle keep the frame comfortable and familiar for shooters moving from a stock Glock. The included Picatinny rail rather than a proprietary Glock rail adds broad accessory compatibility for lights and lasers. Compatibility spans 9mm .40 S&W and .357 SIG making this frame a versatile multi-caliber platform. Builders receive a frame that needs nothing but a slide assembly to complete saving time compared to assembling individual internals from scratch.
