I have a Browning BPS, 3" chamber and I bought it because it fit's me. Most shotguns don't. It is reasonably easy to disassemble and reassemble for cleaning and it will take a lot of dirt [i.e. typical day in the field.] Mine dosn't like all shells Kent empty hulls somtimes jam, Winchester pattern poorly [ type of choke tube in it?] Federal and Remington work perfectly. What's on my wish list is a Winchester Model 12 in 3" chamber if I ever see one. That will last more than a life time.
