Let me put you back at ease about the P226.
The only reason our Military is currently using the Beretta M9 is money. SIG P226 performed as good, or better. In fact, the P226 (Navy model) is the current sidearm du jour for the Navy SEALS.
Look at every major handgun trial in the past, oh, 10-15 years or so, and compare the brands that passed.
Sometimes GLOCK makes the cut, sometimes not. Sometimes HK makes it, but not always.
SIG always makes the cut in every trial I have ever seen. They might not be awarded a contract, due to cost or any other political reason, but they make the cut.
Most recently, they and HK won the DHS contract.
I trust my life to SIGs. I think that they are about as good as you can get in a production pistol.
