The internet gave me some answers to my own question. The gun I inspected was made in Turkey, and as it appeared, is very high quality. I have a CZ double, but the S&W is much finer of finish. It also seems that the original single, nonselective trigger, paired with fixed chokes was not a popular combination, or was problematical from an operation standpoint. This was abandoned in favor of double triggers, simpler, with quick, easy choke selection. Now the gun has been dropped from the S&W line-up. I don't know why but would be interested if anyone does know. I found a new-in-box double trigger model for $1,500 but am unsure of reliability and support. I have read of some unreasonably hard trigger pulls on this gun. Perhaps to prevent doubling as the hard trigger seems to be always on the tighter choke barrel. Any information appreciated. All the above is suspect.
Thanks,
