Can one find out the model differences between a 1086, a 1066, and a 1006?  Maybe it is online somewhere??

Need some parts for a 1066.  1) Adjustable rear sight.  Was a factory option and I have always carried adjustable sights on my firearms used on the job as a LEO.  Present sight is in a dovetail and supposedly driftable (very hard) for windage.  NO adjustability for elevation.

Bought handgun online and was bummed when it arrived with the crappy rear sight.  S&W has none in stock.  It appears from exploded drawing that an adjustable version has SS "ears" protecting the mechanism.

2)  Same gun.  Came with bobbed hammer.  DAO?  I like hammers so it might take the SS hammer part and MAYBE another piece of the action buried deep inside with a sear to engage a notch in the replacement part WITH hammer.

Is it true that some Generation 3 10mm model will accept a double stack magazine??    Thor
