So...I've been having this issue with a new-to-me pistol...the follower seems to drag and does not properly present the cartridge rim to the breechface of the slide during cycling.
Thinking it may be a fouled magazine body, I disassembled and cleaned it up. No joy.
Next, I stretched out the magazine spring a little. Not only NO JOY, but I got to search out in front of the firing line at the range for the plunger for about ten minutes after I launched it inadvertently while trying to reassemble it. I was very popular for the afternoon.
At home, I bought a spare mag off of fleebay because I figured I wanted one anyway (I always acquire a few spares when a new pistol comes my way), and thought I'd just wait to see if the new mag fixes the feeding issue. A little while later, something occurred to me so I removed the mag catch and took a look at how it engages the slot in the magazine body in the second issue pistols, and that's when I took the above photo.
So, has it been demonstrated that the follower spring drags on the edge of the mag catch on some pistols, and is there an established method for determining the correct amount of metal to remove from the magazine catch? I don't want to go figuring this out on my own if someone's already been down this road.
Thanks in advance.
