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.

I had three of the 10 rounders, all this past summer, sourced from different dealers, and I returned all three as none of them would feed.

I tried all the permutations of flipping the spring, the follower, standing on my left foot, et cetera.

No joy. Something is basically defective and there are a LOT of people reporting it.

All four of my 5 round mags work perfectly.

I want at least one larger cap mag but I will wait until I can get one that I know works. Without me having to re-manufacture it myself. Maybe buy it at a LGS where I can try it first or something.
