Yea of course we have all seen the effects of recoil on things staying put and getting beat up. I just think you might be on to something that I had not considered. You have to figure that Colt would have made guns out of cheaper and easier to work materials if there was ultimately no difference, but they didn't. It makes me wonder if all these years when I have seen people inquire about guns that used to work and now aren't if possibly the pin is out of true, or the breech face is uneven and now it's rubbing or catching. I personally have had no problems, and I have shot my plated brass frame Piettas a good deal SASS shooting, but mostly the Rems, not the Colts. I think you have a strong argument.
