Glock 27 Gen 4 OEM Frame

Upgrade or rebuild your Glock 27 with a factory-spec Glock 27 Gen 4 OEM Frame — the serialized lower receiver engineered to deliver dependable Glock performance, compact handling, and Gen 4 modular ergonomics. Ideal for replacing a worn frame or completing a compatible build using OEM-spec components.

Product Description | Specs for Glock 27 Gen 4 OEM Frame

The Glock 27 Gen 4 OEM Frame is constructed from Glock’s high-strength polymer blend, designed to withstand recoil forces from the .40 S&W platform while maintaining lightweight, subcompact carry dimensions. Featuring the Gen 4 Modular Back Strap System (MBS), this frame allows users to adjust grip size for improved comfort and control.

The frame includes integrated steel guide rails and factory geometry required to accept a Glock 27 Gen 4 slide assembly and compatible lower parts kit (LPK). The aggressive Gen 4 texture enhances grip traction without being overly abrasive for concealed carry.

FAQs

Q: Does this frame include internal parts?
Complete versions include internal components. Stripped frames do not. Verify before ordering.

Q: Will a Glock 26 slide fit this frame?
No. The Glock 26 is chambered in 9mm and is not directly compatible with the Glock 27 .40 S&W frame without proper caliber-specific components.

Q: Are Gen 3 parts compatible with this frame?
Gen 4 frames use a dual recoil spring system and updated internal geometry. Use Gen 4–specific parts unless confirmed compatible.
