Hi all - I recently bought a CZ 457 that came with the plastic 5-rd magazine. I don't necessarily have anything against plastic gun parts (or plastic guns), but this magazine does not inspire confidence. It feels cheap in my hand - But if it's "tough enough", then it's tough enough for me. Can anyone comment on how they stand up to field use?

I'm only interested in the 5-rd magazines, but I suppose feedback about the 10-rd mags is relevant as well.

Are the steel mags an improvement? Or just more expensive?
 
CZ makes good, reliable magazines. A now retired gunsmith in the States would even retrofit Anschütz rifles to take CZ mags.
 
That's exactly what I was hoping to hear, thanks folks. Additional comments welcome - And if you know of a good source for 5-rd magazines (plastic or steel), I'd love to hear it.
 
My CZs run smoothly on both polymer and steel mags. The steel might have a higher chance of surviving if inadvertently stepped on and the poly will never rust. They’re both fairly pricey for what they are, so I would just pick whichever one(s) are lightest on the wallet
 
If I was starting over, I'd probably only use the Polymer mags. Light, durable, easy on the fingers, zero reliability issues. Only ever had one CZ steel mag that never ran perfectly. All of the polymer ones have been perfect. The 25 rounder doesn't work in all CZ/BRNOs.

BTW, I normally load my 10 rounders to 8 anyway, as sometimes getting 10 in seems like there is too much resistance. Only ever had feeding hiccups on fully-packed 10 round mags. My experience is with CZ 452, CZ457, and BRNO 2E
 
The steel mags aren't working well for you when the tab is bend inward and pinches the nose of the round. Bend it away with pliers and enjoy the continued flawless cycling. I find them cold and heavy in the winter but no issue at the range.
 
I have several of the polymer 452 mags . and all are super reliable. The only issue I have had is I dropped a loaded mag on the cement floor and broke the slide on bottom cap . A great member from rfc mailed me a new bottom cap free of charge .
 
When I had two CZ452's and later two CZ455's, some information came my way suggesting the Polymer were superior to metal . . . put them both down on the pavement and driver over them.
This was supposedly the test for proving one to be better than the other.

I have only had polymer mags and never had a problem.

I have never had a metal mag but one of the Brno rifles at the club has a metl mag and there are no problems.

I have lots of CZ polymer mags, both .22 and .22mag/.17hmr. I’ve not had any trouble with any of them. I have one each 5 & 10 round steel mags and seldom use them. I bought a .457 .22wmr the other day in a gun shop in Gull Lake, SK, and noticed they had genuine CZ 5 rnd .22lr mags for $29.95. Not expensive at all, I thought.
 
Poly mags are all I use in any of my CZs. Returned my two steel mags shortly after purchasing. The steel mag bodies have a rough surface finish and there's friction between the body and steel follower which can cause a bit of binding, in my experience. The poly CZ mags are super reliable, way lighter, won't scratch the trigger plate if your aim for the mag well isn't perfect, are cheaper, no sharp edges. There are really no downsides.

I have plastic and steel mags for my 452. 5 and 10 round. Never had a issue with the plastics.
I find they are eiser on the thumb when loading and don’t scratch then mag well when you mess up putting it in.

That being said. I “prefer” metal over plastic every time
 
Both types have run 100% flawlessly in my CZ’s for over a decade. If I had to choose one it would be the polymer for the weight reduction without penalty. There’s no scenario (for me) where I’m stressing the mag so much that the strength of the steel becomes advantageous. YMMV.

Here are the weights of my mags, empirically measured, unloaded:
(there’s variance from mag to mag, so these are rough averages)

5 rd Polymer 12.6g
5 rd Steel 52.9g

10 rd Polymer 18.9g
10 rd Steel 80.6g

25 rd Polymer 86.6g
