Keepshooting magazines' nubs worn out and causing failure to feed issues?

[Ignatius]

Last year I bought these keepshooting magazines for my M1 carbine https://www.keepshooting.com/m1-carb...-magazine.html. They worked flawless when I turned the magazine spring into its correct orientation, but suddenly I've been getting failure to feed issues and sometimes the bolt wasn't able to catch the last round. Here's some pictures of the magazine nubs at the moment:




Anyway to fix this according to your guys' knowledge?

round awl and very little small flat file work.

go slowly , bend a little file edge of "nubs" flat , try installing.

might as well replace your magazine catch while your at it . that is what is eating them.

And again , your awful hard on those magazines . I have some that are older than a lot of guys here and they don't look that bad .
