Waddies will now and then present you with ramp fouling in the .45, not too bad if you clean it after every session but that's not always possible in the field. I like them in my .38 spls especially in the summertime; in the winter when heavier clothing is worn I'll go to a semijacketed hollow. With the .45 mine (Colt Commander and Kimber) seem to gobble up just about anything I'm silly enough to stick in there. I have a couple LEO friends who swear by the 185-gr Golden Sabres but I stick with the 230-gr hollows. My gunsmith brother calls them "flying ashtrays."
