I agree with the others.
As long as you're carrying it in a holster that covers the trigger loop, and you don't have your finger in there when holstering, you have nothing to worry about.
In fact, I'd worry more about having the presence of mind to take off the safety in time of need.
When you find that the P226 is too big or heavy to carry, consider the P239. Everything is the same exept the size & weight.
