Features & Specs

The Polymer80 PF940Cv1™ 80% Compact Frame and Jig Kit (Glock® 19/23 Compatible) is built around a reinforced polymer frame with a steel front locking block. The frame geometry gives you a high grip, which improves recoil control and keeps your hand higher on the bore axis. The integrated jig holds the frame securely while you drill the pin holes and remove the polymer tabs. The kit comes with the jig, drill bits, end mill, and instructions. The frame accepts standard Glock 19 and 23 parts, including slides, barrels, trigger assemblies, and magazines. You do not need to modify any parts to fit this frame. The finish on the frame is a textured surface that provides a solid grip in wet or dry conditions.

• Reinforced polymer frame with steel locking block for durability and reliability.
• Includes the complete jig kit: jig, drill bits, end mill, and step-by-step instructions.
• Accepts standard Glock 19 and 23 parts – no special modifications required.
