Solved my problem!
I live in California so works great for the 10 mag. The problem I had was my original magwell had a set screw. Had the frame stippled and when I got it back the guy set it so tight I couldn't even put a mag in my frame. I was able to heat and correct my issue but it was a fine line with the set screw. Sur mag well dosen't have a set screw and all my concerns with my frame are gone. Pricey but well worth it.
