A couple hundred rounds thru my 340 and no wear on the cylinder....a box of 357 also. I tame the beast by holding my grip a bit higher (web between thumb and finger where hammer would be. Just sayin' it works for me. Like a M-80 going off in your hand!
As a LEO back in the 70's I had a 6 inch Python I carried on duty. Blue steel and mean looking, I just didn't care for the action or trigger. Sold it $140 ($10 loss) and bought a model 19. Don't regret the decision but wish I had them both back now
