They're probably a tie for mediocre for that purpose.
Hmm. I don't see it that way. A 10 with maxed flatnose 220's or a 357 with wfn 180's seem like good options to me. Not a Casull, but controllable and portable, with lots of firepower. Defense shooting and retail business have 3 important similarities in order to succeed: location, location, location.
