The Strike Industries GEN3 Magwell for GLOCK G19 was designed to provide easier reloading of the magazine while adding SI styling. With the added front lip of the magwell, this SI magwell gives improved grip support. This magwell is made of high-strength impact resistant custom blended SI Polymer Extreme material. Keeping to the slender factory design of the pistol grip, the benefit of adding a funnel-like magwell to help prevent the dreaded reload bobble outweighs the added material of this SI Magwell. Add consistency and cut fractions of seconds off your reloads now with the Strike Industries GEN3 Magwell for GLOCK G19 while comfortably carrying your pistol on your hip or in your waistband.
