I am interested in buying a model 41 and have found that new ones are very hard to find. Used ones with a 5.5 inch barrel are available in several places but some advertise a "bull" barrel and others just say 5.5 inch barrel. Is there a difference? On S&W's site for the product I don't see anything like this listed as an option.
Also if I buy a used one, what should I be looking for other than external physical appearance?
