SCT Manufacturing SCT-17 Full Size Gen 3 17/22/31 Gray Polymer Frame

The SCT Manufacturing SCT-17 Full Size polymer frame is an aftermarket lower built for Glock Gen3 17, 22, and 31 pistols. Molded from durable polymer in a gray finish, this full-size frame accepts 9mm Luger, .40 S&W, and .357 SIG components, making it a versatile platform for custom Glock-pattern builds.

The frame features an aggressive texture grip for improved purchase and control, along with stainless steel over-molded rails for long-term durability and smooth slide cycling. Designed as a direct-fit replacement, the SCT-17 accepts factory and aftermarket Gen3 slides, barrels, and small parts compatible with the Glock 17/22/31 platform.

This listing includes the polymer frame with an installed locking block. Front and rear serrations along with a trigger guard bump help with recoil control and weapon manipulation. The frame ships assembled with the locking block in place; slides, barrels, magazines, recoil springs, and other internal components are sold separately.
