I got my CZ 24 today, very nice condition. I decided to shoot it, so went to load up the magazine with .380. Hmm? .380 won't fit. Now I'm thinking I remember the CZ 24 was also made as a .32, so I load it up with .32 auto, these fit well, holds 9 rounds. The first few rounds fired I'm thinking "Man, this isn't very accurate!" The hits go from one side to the other about 3" from center at 15 feet! Now, none of the rounds are cycling the action, "Hmm, I guess I got taken" I'm thinking. So I cycle by hand and keep shooting. The seventh round, nothing. The 8th, no fire, the 9th, nada. Then I look at the floor, the cases are ballooned out! I quickly (But not quickly enough!) realize that the gun is a .380 but the mag is a .32 mag from a CZ 27. One of the last rounds that didn't fire has a pretty good dent in the primer, but didn't fire. I open the slide, and there way down at the far end of the chamber sits a loaded round captured by the rim! If one of the last two rounds had gone off it would have been,,,interesting. Yeah, I'm an idiot, at least today. That's the first time I've ever gotten a gun with the wrong magazine.
