Techinical Discussion of Follower Mod

[JFootin]

Continuing with your idea that the higher spring pressure is affecting the second and third rounds, and knowing as we all do that the next round gets pushed forward as a round is stripped from the magazine (more so with the upper rounds), could the front of the bullet be contacting the front of the magazine and, finding some roughness there, hanging up?

Whatever it is, it seems to me like the sanding of the top of the follower to move the pivot point forward should help. But examining the front inside of the magazine near the top for any burrs or roughness would also be a good idea.

Mine tip down as I load the magazine. If you look at the pictures in post #16 you also see that only the top of the rim of each cartridge touches the rear flat of the magazine. This could contribute to a downward torque when loading as the rim tries to lay flat on the rear of the magazine. I think this is a problem in the Kahr magazines because they have a fairly sharp nose up angle. This would be difficult to fix without a total redesign of the magazine to have a rounded rear profile. This might require a redesign of the frame because the magazine well might have to be longer front to back. If I am barking up the right tree, I can see why Kahr might be reluctant to open that can of worms for relatively low number of problem cases. my rounds tip down some but still feed even riding the slide slowly forward.

This is certainly possible, but I don't see why it wouldn't happen with all rounds in the magazine. I did inspect the inside of the magazine, and I don't feel any burrs or rough spots, nor can I see any. I wish like crazy I had a clear magazine so I could really see what is going on as the spring expands.
