PF940SC Polymer Frame for Compact Builds

The PF940SC frame represents a critical component for builders focused on a compact, concealable platform without sacrificing capacity or control. Manufactured by PF940SC, this frame is designed to accept standard Glock 19 slide assemblies and 15-round magazines, offering a versatile foundation for custom pistol projects. As a Category: Frames product, the PF940SC is precision-machined from high-strength polymer and reinforced with steel rails, ensuring long-term durability under repeated use. This frame is compatible with a wide range of aftermarket slides, triggers, and lower parts kits, making it a preferred choice for those assembling a reliable, compact firearm from the ground up.

Overview

The PF940SC frame is engineered for users who require a balance between grip length and slide compactness. Unlike full-size frames, the PF940SC features a shortened grip that accepts compact magazines, while the rail system accommodates standard compact slides. This design allows for improved concealment without forcing the user to adopt subcompact dimensions. The frame includes a textured grip surface with integrated trigger guard undercuts, facilitating a high, consistent grip during operation. All critical mating surfaces are machined to tight tolerances, reducing fitment issues with common upper assemblies. The PF940SC is sold as a bare frame, requiring the end user to complete assembly with a slide, barrel, trigger group, and other necessary components.

Features & Specs

The PF940SC frame incorporates several design elements intended to enhance reliability and ergonomics during assembly and firing. Each frame is manufactured from a proprietary polymer blend that resists impact and chemical exposure. The steel-reinforced rear rail module is pre-installed, aligning the trigger housing and slide lock for consistent function. The front rail system is integrated into the frame, providing a stable platform for the recoil spring assembly.

All specifications are measured from production samples and may vary slightly between batches.

Who It’s For

This PF940SC frame is intended for experienced builders and enthusiasts who possess a working knowledge of firearm assembly and safety protocols. It is suitable for individuals who prefer a compact platform for concealed carry, home defense, or range use.

Builders should have access to appropriate tools, including a vise, punch set, and a drill press or hand drill for pin installation. The PF940SC frame is also appropriate for those who wish to customize their firearm with specific slide finishes, barrel lengths, or trigger weights, as the frame accepts widely available aftermarket components.
