i have'nt shot a lot of it but the mag-tech fmj worked real well for me and seemed to be cleaner than WWB. oh and by the way that "possibility of shots through a car door" statement. have you ever shot through a cars door? well strangly enough, i have, more than once. the place me and my friends usually shoot at is an old abandoned strip mine. and about once or twice a year, teen idiots will jack an old car and deposit the remains there, usually burned or wrecked beyond repair. my buddys and me use them for targets and senario drills and such, and i gotta tell ya, car doors don't stop a hole lot of anything. not even .22's in some cases. I don't think there's a .45 on the market that won't go through a car door handily at close range. I'm not slamming your choice. people have there reasons for what they do. but if you decide to try somthing that expands, i don't think barrier penatration will be an issue. you might take a look at cor-bons powr-ball ammo, a hollow point with a polymer tip in a ball shape that seems to feed like crazy in 1911's. might be worth a look. good luck , hope you find the right one.
