I’ll try that. I may try the lakeline follower for that mag as well. I really feel the mag is over sprung. On an empty and full mag, the 6 rounder is noticeably stiffer than the flush mag. With both mags topped off the top round on the 5 round is noticeably easier to strip off than the 6 round. The gun will feed the top round by riding the slide forward with the flush mag. On the extended you have to drop the slide with the slide stop or slide shot it very hard. If a coil or two were removed from the 6 round magazine I bet it would work better.

There is just far too much frition between the case rim and feed lips. Hopefully radiusing and polishing the inside of the feed lips for the gun to run normally. Something needs to give.
