CZ 457 Magazine Issues….

I’m just curious. . .

How many of you have had issues with CZ 457 10 Round 22 LR Magazines OUT OF THE BOX.

My observations:
  • Magazine ”feels” noticeably different, less smooth when loading after 2-3 rounds. Almost like its binding.
  • If I can load 10 rounds it rattles when you shake it and there is no room to “press down” on the top round to “feel“ it is loaded to capacity.

I recently had a magazine ship with (2) followers and that was the reason it was binding. This was an obvious fix.

I tried taking them apart, depressing the magazine spring and holding it under tension through one of the cross holes, reinstalling the base and letting the spring go under tension to “slap” into place (process some people are having success with when using extensions). This worked on (1) of the magazines…. The other (3) are garbage… waiting to hear back from CZ / Vendor I bought them.

Just saying. - never had a single issue with older 452 metal mags either 5 or 10 round.

On the 457 junk, I have had to ever so slightly file the locking tab upwards until it snaps in properly. I have had to reverse 98% of the springs.

Mecgar or whoever makes them for CZ does a pitiful job.

I have metal mags for all my Brnos and CZs and that's quite a few. I do use the plastique craptastique at the range so if any light finger nicks them im not too upset, and in the field because if I lose one, who cares.
