Grip Force Adapter for Glock Gen 1 2 3 and 4

GEN 4 ADAPTERS
STANDARD & COMPACT GLOCK FRAMES
GEN 4 MODELS: 17, 19, 22, 23
The GEN 4 GRIP FORCE ADAPTER was specifically developed to fit GLOCK's GEN 4 pistol in its base "short frame" configuration. The short frame configuration does not utilize either the Medium or Large factory grip panel on the frame. The GEN 4 GRIP FORCE ADAPTER eliminates the drawbacks associated with permanent modifications to your factory pistol. The GRIP FORCE GEN 4 ADAPTER mates completely to the back strap of the GEN 4 frame, permitting the shooter's hand to conform to the frame in a more secure manner. This offers more control and allows the shooter to index the pistol on target more efficiently.

If you are using a GEN 1, GEN 2, or GEN 3 series GLOCK, you can only use one of our GEN 123 ADAPTERS on your pistol. Both versions of the GRIP FORCE ADAPTER, GEN 123 and GEN 4, can be used on GLOCK’s new GEN 4 series of pistols.

Whatever factory grip configuration the shooter decides to use on their GEN 4 pistol will dictate which GRIP ADAPTER they can utilize on their GEN 4 frame. Those who choose to use their GEN 4 pistol in its short “SF frame” configuration (with no GEN 4 Medium or Large factory grip panels installed on the frame), should purchase our GEN 4 GRIP ADAPTER. This ADAPTER, mounted on a GLOCK GEN 4 pistol, will make it index as if it had a more upright back strap/grip angle. Our GEN 4 ADAPTER is designed to only be used on the "SF frame" of the GEN 4.

Any customer who utilizes the GLOCK GEN 4 factory Medium grip panel on their GEN 4 pistol, must use our GEN 123 ADAPTER over top of the Medium grip. The GLOCK GEN 4 factory Medium grip panel is designed to configure the grip of the GEN 4 pistol similar to GLOCK’s older GEN 3 series of pistols.

***Our GEN 4 ADAPTER will not fit over top of this GEN 4 factory Medium grip panel.

Our GEN 123 Adapter on a GEN 3 series (or older) Glock, will index slightly different than the GEN 4 SF frame/ADAPTER combination.  This slight difference is due to
the shorter front to back dimensions between the standard and SF frames. Our
GRIP ADAPTERS fill in the contour on the back strap of the frame, and create
a flatter area which makes the gun index on target differently.

***Our GEN 123 ADAPTER cannot be installed over top of GLOCK’s GEN 4 factory Large grip panel.

The increased size of that grip prevents our stock GEN 123 ADAPTER from fitting over top of it.  Some end users have chosen to permanently modify their GLOCK GEN 4 factory Large grip panel, along with our GEN 123 ADAPTER, to use these products together. In order to do this, they remove material from the underside of our GEN 123 ADAPTER, and contour it to mate it over top of the Large factory grip panel. They then use epoxy adhesive to permanently affix it to their factory Large grip panel when it is installed on their GEN 4 pistol.  This is the only way one of our GEN 123 ADAPTERS can be used on a GLOCK factory Large grip panel.
