I'm not sure how that's going to help as it does not appear to be touching the bottom of the grip. Anyone else have this issue with an extended mag? If so, how did you resolve it? thanx.
I have two PM40's and as a result two extended magazines. I would never bother to buy another. Mine work fine, most of the time, with the ammo that works best in my gun, but failures to feed are common with several other types of ammo. The extended magazines are just less reliable, in my experience.
Oh, and I have applied all the "fixes" the require reshaping the plastic followers. They helped, so I keep them for range sessions. But, carry them? No way!
Many people just exchange their extended mags for an additional shorter one. This is true of both 9mm and .40 S&W PM series pistols. Kahr will usually exchange the magazine if you ask. That's probably the simplest solution.
If you really want to make the extended mag work, make sure the spring is in correctly so that it holds up the nose of the follower and consider some of the techniques Greg describes in this thread: http://kahrtalk.com/showthread.php?t=1612 Note: There is a lot in this thread. Scan for magazine follower modifications.
Best of luck, sir!
It would be so nice if something made sense for a change.
