Right now my gun is at 300 rounds. I have stopped shooting it. Last week, I sent in an order for 3 spare mags, 5 sets of recoil springs, and replacement grip screws.
I decided to replace the springs in the future at 250 rounds. That's my choice. I just don't want to worry about beating my gun to death. At 10 bucks a set, it is no big deal for me to replace them at 250 rounds. So, that's what I'm going to do.
