"This mount is amazing, I don’t have to worry about drilling holes in my hi-Capa I can just screw it in to the grip and use it instead of a slide lock. Which wouldn’t really matter since I short stroked it. The mount is very stable and I would recommend it 10 out of 10.

Don’t have to drill holes
Easy to install
Really low to the gun
Doesn’t sit really high
Can adjust how far you want the rail forwards or backwards

None at the moment but if theirs any I will get backed
