CZ82/83 magazine problem

[imarangemaster]

I have six 13 round magazines left from my earlier CZ83 I had from 1994 or so until the early 2000s.

-Two are Military CZ82 mags with the crossed swords and the dimples (channels) in the bottom of the sides.
-One is a Military CZ82 mag with the crossed swords and NO dimples (channels) in the bottom of the sides, and the early floor plate lock with the steel "button" riveted in..
-One is CZ Commercial 83 magazine, with no crossed swords and the dimples (channels) in the bottom of the sides (This was the factory mag that came with my 1994 one).
-Two are unknown mags I picked up at a gun show years ago. They have a visible seam, but appear to have CZ followers, springs, and floor plates (with the welds on the front lip of the base folds).  They don't look quite the same as the ones floating around with the fake "CZ mfg"on the floor plate. These mags do function 100%.  Maybe some old foreign contract?

The grief is with one of the crossed sword military mags with side bottom dimples.  It fails to feed the second to last round, hitting the ramp at 45 degrees.  I have replaced the spring and the follower with factory ones from CZ-USA.  The rounds in the troubled mag seem to seat exactly the same in the feed lips as mags in other mags.

My two crossed sword mags also do the same thing--FTF on the next to last round getting stuck before the battery at about a 45 degree angle requiring that you eject the mag and pull back the slide to release the pinned round.

After a thorough cleaning and lubrication the next-to-last round feed problem went away.

Thanks, I should probably do that with all my CZ mags.  I recently did it with my Glock 19 mags and my Bersa Firestorm mags.  Just haven't gotten around to doing it to the CZ ones this year.
