Machined from high-strength, impact-resistant polymer, the PF940SC is engineered to accept Gen 3 Glock 26, 27, 33, and 39 slide and barrel assemblies, giving you a proven platform with the flexibility to finish it yourself.

Overview

The Polymer80 PF940SC 80% Pistol Frame Only is a unfinished frame that requires final machining of the fire control pocket, trigger housing pin holes, and rail system. It is not a firearm and does not require an FFL transfer for purchase, though final assembly and serialization must comply with all applicable federal, state, and local laws. This frame features a reduced 1913 Picatinny rail section for mounting lights or lasers, an aggressive textured grip stippling for positive hand retention, and an integrated trigger guard undercut for improved high-hand hold. The PF940SC is the smallest offering in the Polymer80 compact line, ideal for concealed carry or backup roles.
