Not putting down the Glocks but here in Kansas they don't have a long enough case length in any of the rounds that you've mentioned.
FIREARMS
Centerfire rifles and handguns that are not fully automatic and that fire a bullet larger than .23 inches in diameter and that use a cartridge case that is 1.280 inches or more in length (except that elk require a bullet larger than .25 inches in diameter a cartridge case length of 1.750 or longer), while using only hard-cast solid lead, soft point, hollow point, or other expanding bullets
