Also, the triggers on them CAN NOT be made as smooth as the triggers on the average S&W. I know someone here's going to throw a hissy fit about this talking trash about how nice their Python trigger is, etc. But let me put it to you this way:
Look at the trigger geometry. Anyone monkey with half a brain can see the S&W design has less bearing surface and more mechanical advantage in the trigger. I've never seen a S&W with a hammer mounted firing pin that couldn't be turned into a delightful trigger pull. On the other hand, I've seen lots of pythons with much less than ideal pulls that good pistolsmiths gave up trying to improve on

It's just an engineering fact. S&W's trigger design is BETTER.
Of course, if you want to better compare apples and apples, compare a 1960's era S&W Model 27 to the python. No contest. I'll take the model 27.
