I also have both, I carried the P229 for almost 12yrs when I switched to the XD45. I just picked up a 2 tone P226 and started to carry that instead. Currently I am waiting for the P224 to come out in 9mm SA/DA sometime this summer. It is a smaller version of the 226/229 and can use the same magazines.
But you are correct when you say that you can not go wrong with a Sig Classic series pistol. The are priced alittle high, but you get what you pay for and you are defiantly paying for a great pistol.
