I'm not a fan of Glocks. But I have some questions cause I try to keep up on whats going on gun wise.

What is with the Numbering System that Glock Uses to identify their pistols. Is there a trick to knowing what the caliber is, or, do you just have to learn them.

Example Glock 26, Glock 19, etc... Do the numbers have any kind of meaning?

Next is the Generation thing. 1st Gen, 2nd Gen, What does this mean? Is a 1st Generation any better or worse than a 2nd Generation of the same caliber. What about a 1st Generation of one caliber compared to a 2nd Generation of a different caliber?

Just trying to figure this Glock thing out and it really confuses me.
