Start your new Glock 19 Gen3 build right here with the FMK Firearms® AG1 Frame. It's made from reinforced polymer, and comes 100% complete and ready for a lower parts kit of your choice. The AG1 maintains the grip angle, controls and geometry of the G19, but offers enhanced texturing to help you get a firmer grip. The texture is aggressive—but not abrasive—so you can easily shoot for 3 straight hours without leaving any skin at the range. Additionally, the highly undercut triggerguard allows for a high grip and better control.
