Does what's intended and more!


I got one for my Gen5 Glock 19. The fit was perfect, I used Purple Loctite (Low-Strength) to ensure the screw don't back out over time from recoil. It does its job fine but, I chose it for two other reasons. First with-it being aluminum w/ brass insert, it adds more wight to the gun helping with control over it. Second is with my smaller hands along with the G19 pistol grip length. I'm able to sandwich my hands in-between the top shelf of the magwell, with the bottom of the trigger guard. This causes my hands to get pushed higher up the gun's frame, improving control. Making it pretty much impossible for my hands to slip around or off of the pistol grip.
