in my experiences and those i know the CA bull dog .44spls are a 50/50 gamble of getting a real sour lemon. ive tried two a few decades ago and they both were crap. in fact of the dozen~ or so that ive fired (mine and friend's) personally only two were "good" with the rest having various problems.
good luck! id have no problem paying for one if first i got to shoot 200 standard pressure defensive rounds through it first and examine it afterwards. to this date usually one box of ammo revealed problems that were not "break-in" related.
