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.
SP101 2.25" in 357 mag....I use 38+p+ 110 gr.as a carry load in the summer(soon to switch to the gold dot 135gr)and 158gr 357 mag. in the winter.I carry in a Desantis thumb break holster strong side behind the hip.Speed loader in front pocket.
I just got a Glock 21 about a week ago and carried it all day for the first time yesterday. I wore it in a DeSantis thumb-break holster on my hip at about 4:00, which seemed to conceal it just fine on my 6' 220lb frame. It is a bit bulkier than my G19, but no one seemed to notice but me.
Currently i carry a Ruger P89DC in a Galco IWB with 115gr +P Georgia Arms JHPs. Even a gun as big as the Ruger dissapears under just a tshirt and shorts! Soon (hopefully) it will be a Glock 29 or 30... not sure which one yet.
