The decocker broke on my P226 today when I was running Bill Drills at the range. The gun is creeping up on the 40k rounds fired mark and has who knows how many hours of dry firing. I try to get in 10 minutes a day, so...a lot. I decock out of habit every time I begin to holster the gun, regardless of if the hammer is up or down. In short, the lever has seen significant use and I'm not in the least upset it decided to take a retirement.
I got home, took the grips off, and verified it was the decocker itself that had broken. It had snapped off where the wire spring goes in.
I called Sig's customer service line, a fellow answered on the second ring, and in less than a minute he was shipping me a replacement part gratis. The only questions were to get my serial number and make sure they still had the correct address and email for me (I had this gun worked over by the Sig Custom Shop, so it's already in their system by S/N).
I'll be carrying my P229 on duty for a bit. I think I'll get a 9mm conversion barrel and make this gun a dedicated training gun when we transition to 9mm next year.
