Overview

The Polymer80 PF940SC 80% pistol frame only provides the structural platform for a 9mm or .40 S&W subcompact pistol. Unlike a completed frame, this 80% variant is not a firearm under federal regulation until the end user completes the necessary machining operations. The frame features an integrated, textured grip with a 1913 Picatinny accessory rail for mounting lights or lasers. Built to accommodate standard double-stack Glock 26/27 magazines, the polymer80 pf940sc 80% pistol frame only delivers a compact profile suitable for concealed carry. Each frame includes the polymer body, stainless steel rail inserts, and a locking block, requiring the user to finish the rear rail channel and trigger housing pocket.

• Accepts Glock 26, 27, 33, and 39 slide assemblies and magazines
• Integrated 1913 Picatinny rail for tactical accessories
• Textured grip surface with aggressive stippling for positive control
• Stainless steel front and rear rail inserts for durability
• Compatible with standard Glock lower parts kits

Who It’s For

The polymer80 pf940sc 80% pistol frame only is intended for experienced firearm builders, hobbyists, and shooters who prefer a custom subcompact pistol tailored to their ergonomic preferences.

It is particularly suited for concealed carry practitioners who value a compact, lightweight platform with a proven Glock-compatible ecosystem. Builders should possess basic knowledge of firearm assembly, including drilling, filing, and fitting of components. The PF940SC is not recommended for first-time builders without prior experience with 80% frames or Glock pattern pistols.
