Is this kit compatible with Glock OEM frames?
Yes. This kit is designed for the Polymer80 PF940C frame, which is based on the Glock 19 Gen 3 platform. All parts are cross-compatible with a factory Glock 19 Gen 3 lower receiver, making it an excellent source for OEM-spec replacement parts.
Does this include a locking block?
No. This is a Lower Parts Kit (LPK), which contains all the internal fire control and functional components. The Polymer80 PF940C frame typically includes the proprietary locking block rail system. Always verify what is included with your specific frame purchase.
What tools do I need for assembly?
We recommend a basic armorer’s tool set: a 3/32″ punch for pins, a 4mm punch for the trigger housing, a nylon or brass hammer, and an armorer’s block to securely hold your frame. A Glock tool or small flathead screwdriver is also useful for the magazine catch.
Is the trigger included a standard “Glock-style” trigger?
Yes. The kit includes a standard OEM-style trigger shoe and bar. It provides the familiar, consistent pull characteristic of the platform. Builders looking for a different trigger feel can easily upgrade the shoe or bar later.
