I've had a few; only have one now... 617. My 617 has an obscene number of rounds through it and it has never given me any hint of trouble; absolutely fantastic revolver. I had a 340 J frame .357 which developed WAY more recoil than any .44 or .460 and I could never get it to deploy. I also had a 431 that, while not a .357...it's still a banger you don't want to shoot all day...never a problem.
