Mike, I had a DS 2" unshrouded ejector 32 New Police. It was one of those few but memorable blunders I made. I traded it off because the cylinder latch, shaped like a pawn on it's side with it's bottom end running from 12 o'clock to 6 o'clock really ran from 12:30 o'clock to 6:30 o'clock. Fire three shots ( IIRC ) and the now set-back fired case rim would catch on the cylinder latch. It was the '70s, I was in my 20s, and it didn't seem worth putting up with the hassle of getting it fixed.
Tom B, another reason for better accuracy by the Colt is it's faster rifling twist. Colt was something like one turn in 14 inches, S&W one turn in 18 point something inches. Might not be the exact numbers, but close. That was one reason ( during the days of PPC competition when Pythons were bought and shipped unfired to gunsmiths to pull the factory barrels off and replace them with Douglas or other bull barrels ) that with a cheap supply of extra Python barrels they'd fit them to Smith K-frames, creating the legendary Smython to drool over.
