Features & Specs

Each frame in the Polymer80 PF940Cv1 80% Compact Frame and Jig Kit (Glock 19/23 Compatible) – 3-Pack is manufactured from a proprietary polymer blend that resists impact and environmental stress. The integrated jig kit ensures accurate drilling of the three pin holes, the trigger housing pocket, and the front rail channel. No specialized machining equipment is required—only basic tools such as a drill, router, or hand files.

• Manufacturer: Polymer80. Category: Frames. Compatible with Glock 19 and 23 Gen 3 slide and lower parts kits.
• Includes three unfinished PF940Cv1 frames and three reusable jig kits with drill bits, alignment pins, and instruction templates.
• Reinforced front and rear rail systems with stainless steel inserts for durability and consistent slide cycling.

The frame features an extended beavertail, undercut trigger guard, and textured grip panels for improved control. The jig system indexes directly to the frame geometry, reducing the margin for error during finishing. Each frame is serial-number-free until completed by the end user, as permitted by federal law.

Shipping & FFL

The Polymer80 PF940Cv1 80% Compact Frame and Jig Kit (Glock 19/23 Compatible) – 3-Pack ships directly to your residential or business address with no FFL transfer required at the time of purchase. Because the frames are not yet functional firearms, they are not subject to the same transfer regulations as completed firearms. However, once you finish the frame, you are legally required to ensure it is not manufactured for sale or distribution without a valid FFL. We recommend verifying your state and local laws before purchasing, as some jurisdictions restrict or prohibit the possession or completion of 80% frames. This product is intended for personal use only and must not be transferred to another party after completion without compliance with all applicable laws.

• No FFL required for shipment. Ships to all states where legal. Signature may be required.
• You are responsible for knowing and following all laws regarding manufacture and possession of unserialized firearms.
• FFL transfer disclaimer: This kit is not a firearm and does not require an FFL to purchase. However, upon completion, the finished frame becomes a firearm and must be serialized and transferred through an FFL if sold or given to another person. Polymer80 and this retailer assume no liability for misuse or noncompliance.
