Polymer80 PF45 80% polymer large caliber pistol frame, the first and only 80% frame on the market that's compatible with the Glock G20SF and Glock G21SF components. Keeping with Polymer 80's traditional frame style, it's built with a high strength reinforced polymer construction and has enhanced ergonomics and features. This 80 frame has a more vertical grip angle as well as an aggressive grip texture that covers a larger area of the grip for improved positive control. For states that require serialization this frame has a blank serialization plate that can be used to engrave the appropriate information onto it. The Polymer 80 frames have a double undercut trigger guard, extended beavertail, and full Picatinny/STANAG compliant accessory rail. This 80% frame kit comes complete with the necessary polymer jig, drill and end mill bits, Stainless Steel locking block with hardened pin, and Stainless Steel rear rail module with hardened pin. It is compatible with Glock Gen3 G20SF and G21SF slide assemblies, magazines, and lower parts kits. Check your local and state regulations for ownership of 80% frames and receivers.
