I carry a Glock Model 30 with 10 CorBon .45 ACP 185gr +P JHP's with a velociry of 1150 fps and 543 ft/lbs of energy. I keep it in a Bianchi leather IWB holster if I have loose fitting pants or if the pants are more snug, I go to my Fobus GL4 Kydex holster. I also have an Old World High Ride belt slide holster
as another option.
I'd love to get a SOTB rig too. I always try to keep a extra magazine in a belt clip mag carrier from Uncle Mikes or someone else.
