Features & Specs

The Polymer80 PF940Cv1 80% Compact Frame and Jig Kit (Glock 19/23 Compatible) – 3-pack provides the same precision and durability as the single-kit version, but in a triple-buy format.

The included jig guides every critical cut, ensuring proper alignment for the trigger housing, fire control pocket, and pin holes.

• Compatible with Glock 19 and Glock 23 Gen 3 slide, barrel, lower parts kit, and magazine
• No serial number required to complete; finished frame is not a firearm under federal regulation when sold as an 80% receiver

• Frame material: Glass-reinforced Nylon 6/6 polymer with textured grip pattern
• Includes 3x jigs, 3x drill bits, 3x end mills, and 3x stainless steel pin sets per kit

Who It’s For

This 3-pack is intended for experienced firearm builders who want to construct multiple compact pistols for personal use, training, or as backup builds. It is also ideal for advanced hobbyists who prefer to keep a spare frame on hand or who want to build identical platforms for different calibers (9mm and .40 S&W). Because the frame is sold as an 80% component, it is not classified as a firearm by the ATF, but the end user must ensure they are legally permitted to manufacture a firearm for personal use in their jurisdiction. This kit is not recommended for first-time builders; prior experience with 80% frames or AR-15 lower receivers is advised.

• Experienced DIY firearm builders who want multiple builds from one purchase
• Shooters who want a backup compact frame for their Glock 19 or 23 parts
• Anyone who prefers to complete a firearm without government serialization, where legally permitted

Shipping & FFL

Because the Polymer80 PF940Cv1 80% Compact Frame and Jig Kit (Glock 19/23 Compatible) – 3-pack is sold as an unfinished 80% receiver, it does not require transfer through a Federal Firearms License (FFL) dealer. This item ships directly to your residential or business address with no background check required at the time of purchase. However, you are solely responsible for verifying that owning, completing, and possessing an unserialized firearm frame is lawful in your state, county, and municipality. Some states and localities impose restrictions on 80% frames, including California, New York, New Jersey, Connecticut, Washington D.C., and others. By purchasing this kit, you certify that you are legally eligible to possess firearms and that you will complete the frame only for personal use, not for sale or distribution. We reserve the right to cancel any order that appears to violate applicable law.
