You can get the glock in any size chambered for the .357 SIG round, their 31, 32, or 33 model. It's actually not very popular and is not a cheap round to shoot. Wal mart, when they have any, sells it for over $15 a box and shooter's paradise has range ammo for 14, way more than 9mm or even .40. I love it though and feel it is well worth it.
