What makes the “Compact Long” (PF940CL) frame unique?
The Polymer80 PF940CL frame is a hybrid design that accepts full-size Glock 17 magazines and slide assemblies while maintaining the shorter, more concealable grip length of the Glock 19. This provides superior magazine capacity and a full firing grip while keeping the overall height manageable for everyday carry, offering the best of both worlds in a single platform.
Is this kit compatible with a red dot optic?
Absolutely. The included slide is precision-milled for the Trijicon RMR/Holosun 507C optic footprint, one of the most popular patterns on the market. This allows for direct mounting of a micro red dot sight without the need for an adapter plate, ensuring a low-profile, secure fit for enhanced rapid target acquisition.
What parts are needed to complete this build?
This kit includes the complete upper assembly (slide, barrel, recoil spring, sights) and the Polymer80 frame. To complete a functional firearm, you will need a lower parts kit (LPK) for the PF940CL frame and a magazine. All necessary pins and rails are included with the frame. Basic gunsmithing tools and knowledge are required for assembly.
What are the benefits of the long slide and barrel?
The 6.02-inch slide and barrel provide a significant increase in sight radius, allowing for more precise shot placement. The longer barrel also increases muzzle velocity, which can improve terminal performance and aid in competition scoring. The extended slide mass contributes to a smoother, potentially flatter-shooting recoil impulse, aiding in faster follow-up shots.
