cz75b 9mm & .40 mags interchangability?

[pardonmynoob]

Breaking laws is not what I'm looking to do. Just access to buy a decently price legal magazine.

Thanks for the links and advice guys. I am on the Greg cote notification for proper mags, but have a 40 10rd in the mail anyway purchased based upon info in old threads. Guess I'll see what happens.

The ones for the small frame witness will fit, $25 from midway

Thanks for this, after searching around it looks like this is confirmed.

I have both guns, cz75b and the small frame witness, I run the mags in both guns and haven't had any problems

Librarian has commented on using .40sw 10rd magazines that can also feed 9mm in the magazine sticky post #4: Magazines: all the answers you need

It's perfectly legal to own or use since it complies with the 10rd capacity for the caliber it was made for, but would make sense in owning a 40sw caliber gun that can use these magazines. Otherwise how can you explain why you have them or maybe you just shut up and don't talk to LE other than that you own them.

I think the inside scoop from Stuart from czcustom is that they run just fine (the mecgar blue follower ones). I think I may have read that they are identical to the 9mm mags besides the mag body markings. Same feed lips and follower I heard.

This is not based on my own personal comparison. I'm just regurgitating something I THINK i read.

Not a good idea.

Substantially different specifications on the feed lips on a 9mm magazine compared to a .40 cal magazine. They are NOT interchangeable. The 9mm bullet is .355. The .40 is a true 40 caliber. While you may be able to get away with it once in a while it is definitely not a good idea.

The allowable dimensions are:

9mm .325 to .335
.40 .360 to .370

The older mags would work 90% of the time, but 10% of the time they will stove pipe. I think it's because the feed lips are wider on the 40 so the rounds tend to flip up. Basically, you could do it for training purposes but don't rely on them. Personally, I wouldn't want to explain to a cop how I got those extra rounds in there. It's not a good idea to go there. Just get the proper 9MM mags and call it a day.

just buy another 9 mm CZ, you'll get two more mags

Ding ding!

That is a practice I would not get used to, if you are found with a higher capacity magazine things can go bad for you in a hurry

Some of us have legal preban mags and do not condone illegal behavior. They should just do away with the 10 round limit, it's not saving any childruhn.

the 40 cal blue follower mecgar anti-friction finish and 9mm stamped ones work just fine in my SP-01 and P-01. The ones I had were the same dimension in every way when i did this a couple years ago.

No, .40 will not work properly in a 9mm.
ask me how I know.

from my personal experience, the mecgar CZ 40 cal and 9mm mags are identical and have had no issues with them. no stovepipes either. dont know about the 40 cal oem versions.

Got the .40 mec gar mag and took some comparison shots, pardon the potato shots.

So the 9mm and .40 Mecgar AFC mags are basically the same? Hmm, I should go test this theory out.
