I agree with TK5o. The P226 is my go to. In my last job, I carried a P228 for 13 years and put thousands of rounds through it in training. It NEVER failed me. I have confidence in the P series SIGs same as the 1911. They go bang when you need them to.
I carry the little 365 now and am very happy with it too.
Best for what purpose? If it's just a wide open: I'm a big fan of Sig TACOPS 1911s (forged steel frame/slide), not the Tacpac with cheap holster pkg. They are not often my primary CC.
