Features:

1. Made of high-quality aluminum alloy, it has a very comfortable touch and is sturdy and durable.

2. CNC machining and shaping, perfectly fitting the size of the pistol, greatly improving the speed of magazine replacement and shortening the time.

3. Fixed with metal blocks and screws, it can be stably fixed on the pistol without worrying about falling off during use.

4. Sets of heavy metal blocks can increase the weight of the pistol tail, and switch to recoil force.

Function:

The aluminum Magwell for G20SF and G21SF Glock handguns was designed to fit the SF version of the Glock G20SF and G21SF models. The "SF" models will not fit the new GEN 4 models.

Increase the speed of your magazine reloads with a larger "Big Mouth" to fund the magazine into your large frame Glock. These magazines 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 additional weight will help you tame the recoil. No modifications needed to install on your Glock.
