Frame mounts for Glock

Glock frames have a standardised accessory rail that accepts frame mounts adding weight in front of the action. The physics are straightforward: more mass forward of the trigger guard shifts the balance point toward the muzzle, which works against the rotation that causes the front of the gun to climb after each shot. Across a fast string of fire, that means less muzzle rise, faster sight return, and a smaller window between when you can fire and when your next shot would be accurate.

Rail dimensions are consistent across full-size and compact Glock frames, but frame mount design varies. Confirm compatibility with your specific model on the individual product page.
