XD40 full size and like a few others Black hawk serpa BUT i dont like to conceal that holster its my OC weapon/holster. I find my shirt gets in the way if I "conceal" under an untucked shirt. I have a kholster I use with a SW99 40 for CC. Again I'll repeat what others have said I wouldnt get rid of my XD for nothin. I even shoot targets at 25 yards (not feet) no problem and I am by no means a "expert/marksmen"
