About this product

Glock® Compatible 19 Gen 4 Lower Parts Kit: Build Your Custom Pistol

We take stock Glock® compatible 19 pistols and mod and customize them extensively. Similar to how the AR-15 is the most customizable rifle, the Glock® compatible pistol leads in handgun customization. While most parts target Gen 3 versions, building a Gen 4 Glock® compatible 19 is gaining significant traction.

This comprehensive lower parts kit includes all necessary components to make your frame fully functional and ready for further customization. It is specifically designed for compatibility with the LWD Freedom Wolf 80% frame and other Gen 4 Glock® 19 frames, ensuring optimal performance. Note: This LPK is not compatible with Polymer80 products, which are Gen 3-based.
