I like both the P226 and the 92FS / M9, however I really do not like the placement of the Beretta's safety / decocker. If I had to choose one it would be the SIG, I rarely shoot the Beretta these days, both work tirelessly but the SIG is just a better all around pistol IME. For years the SIG was my HD weapon, but I decided I wanted to add a weapon light, but no rail on the SIG. Actually only have one pistol with a rail, a G34 Glock. It is set up for USPSA competitions and it does not have Tritium night sights. The SIG out shoots the Beretta but the G34 shoots circles around both, all run flawlessly. I have retired the SIG from nightstand service, G17 with Trijicon night sights and a Surefire X400 weapon light/laser has taken over that task. If I could only own one pistol it would be none of the above, it would be my Custom Shop STI 1911 9mm, bet a SIG X5 might just shoot just as good as the STI, but I can't see how any pistol could.
