Glock Beavertail Backstrap Set – Black, G19 Gen4/Gen5

The Glock Beavertail Backstrap Set provides a modular solution to adapt a pistol’s grip to an individual shooter’s hand size.

The kit is finished in black polymer and is intended for use with compatible Glock frames that accept the Modular Back Strap (MBS) system. The set includes multiple sizes to alter trigger distance and improve hand fit.
