I had to sand my follower smooth on the sides and bottom because the follower was catching on the extension. It is common for a little fitting to be needed. I have one on a mag for my P3AT and my LCP. I had to do the same thing to the LCP mag as well.
Thanks Bill...I was all hosed up. I had the leg on the inside of the mag. Once I realized that and beveled the bottom pieve grooves a lttile with my little file...She works great!!!! Thanks for the help.
