Update -- I am just back from the Rogers School. My 2012 226R just passed 8,590 rounds since new, and has yet to experience a single stoppage. I have really enjoyed the process of beginning to learn how to shoot the Sig these last few months. In fairness, I think it is more demanding to shoot at a reasonably high level than, for example a Glock, but it is a wonderful platform for someone that values the Sig's attributes.
GJM, are you still primarily shooting your P226 or have you gone back to Glocks and HKs? If you're still on the SIG, is it still running flawlessly? I've always loved SIGs but by the time I was old enough to buy handguns, it was the heyday of SIG's quality control problems. I'm seriously considering dropping the cash for a P229 SAS or one of the M11-A1s.
All my Sig pistols ran great, and I don't recall a single stoppage or other issue through the whole process. I believe learning the Sig DA trigger made me a better everything trigger shooter.
For now I am shooting a Glock 17 for training and lower 48, and carrying a Glock 22 with a KKM barrel and hard cast loads in Alaska.
