SIG Reliability
Well, in the 15 or so years I have used SIGs, nothing broke that I could have fixed. So I recommend buying more ammo and mags, not springs or firing pins, etc.
Now you are thinking "what does he mean about nothing he could fix?". Well, the frame rails on my P226 cracked, and SIG replaced the old, well used gun for a brand new one. No charge, of course.
