I own two newer Sigs, both P226, neither EVER a problem. Closest "problem" I had was hitting the magazine release once when I first got it. Worked my hand position and never a problem again.
It won't cost you 1K either.
Are you buying local or online? Got both mine off GB. Did me better than any local place.
Lots of people talk about the "older Sigs" being so much better than the new. May be true but mine are flawless so don't know how to be better than that, plus they have a rail.
