So I have to say, after getting this SV grip I felt like a noob. The tolerances on parts like the magwell pin, magazine release were super tight. I actually had to use a punch to get the mag release out. I thought I was loosing my mind. All in all I am very happy with my decision. I received the grip one day shy of a month. Called SV, a couple times and was helped very promptly. All in all a great learning experience. And every single magazine I have, about a dozen old style SV magazines, 4 STI gen 2 magazines, 1 mbx magazine, and one 1st gen magazine. All function and drop free. Thanks for all the great answers. Here is how it turned out. Sent from my SM-G975U using Tapatalk
