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 have purchased 2, 10 round magazines for my 457 in 17 HMR in the past month and both have had the sam issue of not completely seating in the magazine well. I made both of them work by filing down the notch on the magazine that catches on the magazine catch. Quality control on these magazines is very sub-standard.
