i use alot of lead ammo which is from ultramax, which is a bad idea in your glock unless you have an after market ss non polygonal rifled barrel, but it will be fine in your kimber.
blaser brass, is another good option too.
for the ar alot of folks are gonna say stay away form wolf and comm block ammo, ie steel case ammo, i shoot it in mine and i have no problems, to each his own.
