Well, you're going to need to keep track to know when you've arrived at 10k rounds, just like you would to know when you've reach 5k, no? Pro-actively changing out a recoil spring every 5k is hardly an indication of anything being inferior - it's just basic and common good gun maintenance. What does a recoil spring cost?Yes Sir, that is correct. But if I know this going into it, I personally would go to a different gun. I had and loved a Sig 1911 but after less than 2000 rds the recoil spring started to fail. In my profession. I would not take/carry a pistol that I had to keep records of how many rounds I fired though it just to make sure I replaced the spring before it failed. I could consider replacing after 10,000 rds but not much less than that.
