Indeed. I've got no problems whatsoever with the slidestop, shooting 3.000 to 5.000 rounds a year. It's probably because I replace the recoil spring once a year. I know of several guys who didn't and as a result had a broken slidestop...
I don't doubt your honesty, so don't think I'm questioning you, but..
I don't see how a weak recoil spring can cause a slide stop breakage. The weak spring would allow more force to be transferred to the frame as the slide slams back (when the slide stop is not involved), and the slide would come back forward LESS FORCEFULLY on the return part of the cycle, when a heavier or fresher spring would add extra force. It's when the slide slams closed that the slide stop takes the force of the slide, not when it goes back (while ejecting the fired round.)
I suspect the guys with the broken slide stops had something else going on that caused slide stop breakage.
That is not to suggest that you shouldn't keep changing recoil springs, etc. Just don't expect it to save your slide stop.
