GLOCK® 19-compatible. Improved ergonomics. See-through jig.

Fabricating your 80% frame is easier, thanks to Geisler Defence's unique take on the 80% frame jig. It's completely transparent, allowing for more precise fabrication and drilling. When finished, your Geisler frame will provide that legendary GLOCK® reliability in a package with some subtle upgrades: An under-slide Picatinny rail provides real estate for attaching your favorite tac-light or laser, while an updated grip design provides more comfort and control.

This 80% GLOCK® 19-compatible frame works with all factory Gen 1 to Gen 3 components.

Completing Your Frame

In addition to the jig, fabricating your frame requires some basic tools.  This kit does not include the other parts required to assemble your pistol once fabrication is complete. View parts kits here.
