I used to wear my Sig 1911 only during the winter, but am starting to carry it all the time now, partly because I don't care if it prints or not (under reasonable circumstances here in ɐpıɹolℲ ;) ). The only drawback I see to a full size is the additional draw time or switching up to it from a 3". If you have only carried a full 5" you wouldn't notice a difference, but I find myself fumbling the draw occasionally now that I have about 3 more inches on the total length.
