I’m not sure if you’ve made your choice yet but here’s my take. I retired (well, more like just taking a break from work after 33 years of full time work) this spring and decided to buy guns. Lots of guns. I’ve been a veritable Hoover of handguns in the past six months. Obviously I’ve handled many more than I’ve bought. One revelatory aspect of my buying spree has been this shocking truth - there is tremendous variability in quality between different examples of the same model. In my experience, S&W revolvers have exhibited more variability than either Colt or Ruger. Out of over ten S&W 686s and +s that I have handled, only one had a DA trigger less than 12 pounds. Most others were off the scale but decently smooth, while a few others yet were heavy and crunchy. One new 586 “classic” I tried had a sublime trigger - 8.5 lbs DA and 3.1 lbs SA. SA triggers were all excellent but a few had a little hitch of creep before the hammer fall. I ended up not being sufficiently pleased with any of the 686s and didn’t buy one, but I did find a 629-6 4” and a 66-8 2.75” that were just about close to perfect so I bought those. I am still thinking about that humble 586 as it’s just so damn good, but the sort-of fake looking blue S&W is doing these days turns me off. Maybe I’ll get it and have it hard chromed or blued by Ford’s.
Now on to Pythons. The Python “tumbled” finish is far superior to my eye than the “scotchbrite” 800 grit brushed finish of the stainless S&Ws, ut that’s a matter of taste and not function. The beefier frame of the Python appears to offer the same or more strength than the 686. Colts feel different in the hand due to the grip geometry and either they point naturally or they don’t. For me, it works. The DA pulls on all the Pythons I examined were significantly better than the 686s I sampled, and ranged from 7.5 lbs to a hair over 9 lbs but all were smooth as glass. SA pulls were also variable and has been mentioned, the trigger/sear/hammer engagement geometry is done to favor drop safety. Even so, I was able to find a 6” and a 4.25” with SA pulls that were crisp and under 4 lbs. I bought both, along with a 6” Anaconda that is just perfect. My verdict? The new Pythons are better guns than current 686s and, to me, were worth the premium. I like S&Ws and want to get a 686 but I’ll wait until I can find one with a good trigger from the box. But my strong advice would be NOT to buy either sight unseen as, again, there is so much variability between examples. Try before you buy!
