If all i had was a BP revolver then i would use it, but if i had a modern centerfire, be it semi-auto or revolver, i would definately stake my life on it rather than the C&B. My personal choice for a carry gun is a 4" 7 shot. .357 mag. I just prefer the safety, and reliability of a revolver over a semi-auto, and figure if i am in a situation where 7 rds. of .357 isn't enough, that i shouldn't be there in the first place. Under any circumstances, unless you or someone else is in immediate life threating danger, your best bet is to leave the scene. Otherwise you may find yourself behind bars for quite a spell. In todays anti-gun Politically Correct society, even using a gun in self defense is frowned on. You better be real sure your life, or someone elses is in REAL danger before you use a gun, and then you better be sure there is only your word for it when the police arrive. Don't leave the other person as a witness. Sounds harsh, but it is a harsh world, with too many Lawyers in it.
