OT: difference between 9mm, 9mm luger, and 9 x 19 ammo

If a feller has a 9mm pistol are all the above ammos ok to fire in it?

Yes. The 19 refers to the 9mm case length in milimeters.

KEH

9 X 19 yes. 9 X 18 (Makarov), NO.

As far as I know!

Better yet, post your question on reloadbench.com........ guys over there know all the answers!

There are many cartridges in the 9mm family, including .380, .38 Super, 9mm Parabellum, 9mm Kurz, 9mm Makarov and 9 x 21. They all fire a .355" diameter bullet.

9mm Luger, 9mm Parabellum and 9 x 19 all refer to the same cartridge.

I just passed my restricted and non restricted tests today. If you don't know the answer you should not have a gun until you pass a test to show you are qualified.

The Makarov is actually a 9.3mm. It uses a .364" diameter bullet. However if someone was to chamber and fire one in a decent quality 9mm Luger (unlikely) nothing espically bad will happen.

this is the USA we don"t have to prove anything it is his constitutional right to own a firearm.

Don't think what has happened in every other country can't happen to you.
There are many in high places of power who want to disarm you, constitutional rights or not.

buickanddeere, you are right. But isn't it ironic that the people in high places that want to disarm us for the most part have security provided for them. As the saying goes "Politicians love unarmed peasants".

When seconds count the police are only minutes away!

I have found it is much easier to carry a gun, Cops are too heavy.

If you honestly think that the place to learn that type of thing is on some government test I have a bridge you'll be interested in.

Seems to me that when one doesn't know the answer the thing to do is go right ahead and ask like KYfarm did.

So how is he supposed to find out if he doesn't ask?

This post sounds like a juvenile game of "I know something you don't know".

9x19 is metric standard terms for what is often sold in US marked 9mm luger, sometimes marked 9mm Parabellum- same basic cartridge but US SAAMI specs for 9Luger are lower pressure than NATO spec 9mm Parabellum/9x19 which is often found as "surplus" 9mm Luger basic .355 bullet weighing 125 grains as a round nose traveling about 1050 FPS- bare subsonic speed. NATO spec has a 116 gtain bullet sort of truncated cone semi round nose moving 1200+fps- supersonic bullet with a crack on firing. 100 grain bullet exist- old Illinois State police load at 1400fps meant to penetrate car doors. These basic ball/full metal jackets. Lead round nose exist for Luger load at SAAMI spec, Lead nose and hollow points for the NATO spec pressure popular. Super Vel load was a 100 grain hollow point, 147 grain variations at bare subsonic speed with hollow points and exposed lead, segmented jackets/rapid expansion under couple names- Black Talon was among first. Main other 9mm cartridge to worry about is old 9mm Bergman adopted by Spanish as 9mm Largo- Star and Llama pistols were imported in that size as 9x23, some with dual chambering for .38 Colt Super. Astra 400 also chamber for the 9 Largo and they were sold surplus in US. South American market pistols for police and civilians often chambered for it, some of those pistols ended up in US. Short cartidges include old 9x18 browning, 9mm Kurz with the .355 bullet and as mentioned the Soviet Markov 9x18 with .364 bullet- same size as 38 S&W, British 38 Enfield revolver bullet. RN
