Glock 17 is the Glock that started it all, has a lot of different mods for it perfect size and not to big or small very accurate
the.40 has a lot more kick harder to control a 9mm with some trigger mods it's like shooting a 22(kind of)
2.34 mm calibre which is the smallest rim fire ammunition in the World.

The NAA .22 Short is the World's smallest and lightest five-shot Mini-Revolver.
