python has a different spring (scissor style) vs coil spring in the smith. I have had a lot of smiths; still have some; none as smooth as a python because of the spring difference. we can argue on what side of the bread needs the butter. imo the python was the best mass produced wheel gun made. Especially in the 60's thur 80"s (there are a lot of boutique gun makers now). as for wear….mine have all been safe queens and the smiths / rugers were work horses.
