Hi...Somethinzfishy here. First of all I am totally new to the whole firearm scene and have been spending months doing research into what a first handgun would be. I am 35 years old and my brother in law finally talked me into the whole thing. I am very interested in purchasing a G19 and everyone here seems to love them so my question is about that...
Ok dont kill me here but I have stupid newbie bullet question...
On when you look at the specs for models when you read the info on the G19 it says caliber is 9X19...Ok so its a 9mm...
But just for fun when I look up prices on ammo and what it is going to cost me to shoot I'm confused because there are 9mm " choices ".
9mm - 9mm 9X18 - 9mm Luger and a few more I think so....
As far as a G19 goes if I'm thinking about buying one and of course learning how to shoot the right way and have training at a ranger and all that......what caliber exactly does a glock 19 use because I'm confused ?
Is there the option of 9mm but with different lengths or something ?
Also for a beginner at a range learning the ins and out of the sport and target shooting what is a good round for a G19?
I am aware that th ranger guys say to come try out different guns before making a final decision so I get that but Geeeeeezzzzz these G19's look so darn nifty !!!
But again and please excuse the long windedness what exactly does a G19 use - round wise ??

Others have perfectly covered what the Glock uses, but I'll just add, that almost all references of modern guns being chambered in the 9 mean 9X19 Luger.

The only ones you'll probably consider using are the 9X17, 9X19, and 9X25.
The 9X17 is almost always referred to as the .380 and the 9X25 Dillon is a very fast round that can be used in 10MM guns with the appropriate barrel change.

IIRC, the 9X21 is a 9MM designed for Europe where "military calibers" are often outlawed (9X19 is a NATO standard round). The 9X23 Largo is an old caliber originating in Spain, and no longer used much. The 9X18 Makarov is a Russian round also not very popular. Out of the East Block rounds, you'll probably encounter the 7.62X25 Tokarov more often. There are also a couple of others. I think Winchester or Remington experimented with a 9X23... don't know if they had any success.

Note that the bullets in many of these rounds are slightly different. They vary in weight, shape, and diameter.
