This mag is identical to the factory mag that came with my 452 ultra lux. Works good and Buds ships fast.

These are a great mag and work perfect in my 457. I've actually tried an older metal 5 rnd mag in my gun and I experienced a failure to feed. These have never let me down over thousands of rounds. My only gripe is the price. Cz must make a killing on these.

I love the extra capacity

I was a little concerned that these might not work well in mu CZ 455 with the Lilja barrel (one of my 5-rounders doesn't feed well). But they work just fine,

I purchased a second magazine for my CZ 452 ultra lux. Yes these magazines are plastic but after having used them regularly for over 2 years with no breakage or malfunctions, I think it safe to say that they are very dependable, if not aesthetically pleasing.

CZ makes great products. Seldom, if ever, do you experience a failure and these mags are no exception.

Received as advertised, good price and fast shipping. Will buy from again. SFC K.

The CZ 455 American is a 10 out of 10 rimfire rifle. Excellent in every way. These 10 round mags are a 1 out of 10. It's hard to understand how CZ could make such a fine rifle and such a crappy magazine. I bought 5. Stupid me. Two of the 5 have springs so weak they won't feed and the other three are often difficult to load -- for some reason they get stuck. If they were highly used maybe I could understand but this was my very first use of them at the range. And besides all that, the extended protuberance from the stock is right in the spot where you want to place your hand. These are going up for sale on eBay and I am going back to the 5 rounders.

Expensive for what it is, but functions perfectly.

It works as it should but is horribly priced its complete plastic in nearly $40 ridiculous
