Now available for Generation 4 G20, G21, G40 and G41 large frame Glock handguns. The Gen 4 magwell will not fit the Gen 1-2-3 models. A new design is now available for the GEN 4 receivers. Order this Gen 4 model for the "new" G40 and G41 models.
Increase the speed of your magazine reloads with a larger "Big Mouth" to funnel the magazine into your large frame Glock. These magwells are made of top quality aircraft aluminum.
Each magwell includes a brass insert to add additional weight to your Glock's receiver. The addition of the 3.7 oz of additional weight will help you tame the recoil. No modifications needed to install on your Glock. Excellent for use in IPSC, GSSF Unlimited and Steel Shooting.
Due to the size of the stock magazine basepads, stock magazines with stock basepads will not allow the magazine to seat when this magwell is used. We recommend either the CARVER Tactical Extended Basepad, TF Extended Basepad or Arredondo mag extensions for use with G20/G21 magazines when used with this magwell. These basepads are sold on our CARVER Custom website.
