How do you tell the difference between 9mm ammo intended for pistols and that meant for carbines and subguns? Apparently this hotter ammo will chamber in pistols, but shouldn't be used in them.

Thanks

Only sub-gun only ammo I'm aware of was the old IMI Black-tip (FMJ bullet with black coating of some type on bullet). As I understand it thier newer stuff is not nearly as hot and a lot of guys even used the old stuff in better pistols without any reported issues.

Hoping we can get a bit better history lesson on the this from folks more knowledgeble than myself. Thats just my 2 cents as I recall it. Many have learned to not take my memory as gospel;)

I wish that I could find an article on a certain type of Hirtenberger 9mm ammo that I just saw...

It talks about this in great length.:(

I honestly don't know that one. I can say that the 147 grain bullets are the choice for shooting through my suppressed MP5 because they do not break the sound barrier.

Yup,

Subgun ammo is usually 147gr & heavier. Not that pistols don't do well with heavies as well.

Let me explain my question more fully. I've been told that the reason the Beretta 92F was modified slightly to the FS was to "catch" the slide and prevent it from continuing backward and off the frame if it the locking block broke. This was said to be an issue if military personnel used 9mm ammo that is intended for "subguns and carbines" in their pistols. I had never heard of this myself. It implies that NATO uses different 9mm loads-- one for pistols, another for subguns.
