Well, I was going to have Nick at Indy gunworks do this but I did it myself. I'm a hands on kind of person and the more I learned about the process I had to try it. I experimented on a mag base plate that I was no longer using, it looked ok so I got out a file and took off the finger grooves that didn't fit me. That was nerve racking! I didn't take them all the way down, I made them feel right to me. All said and done, it was well worth it, it feels much better. What do you think, good or bad? Remember it was my first!
