The 1911 is a great carry option with 7 rounds of .45 ACP vs 7 Rounds of 9mm. I think the P938 is much easier to conceal though. The issues I have with the 1911 Ultra vs. the P938 is the 1911 grip angle seems to be more likely to print making it more difficult to conceal and also the grip tends to stick into my side making it less comfortable to carry. But I think that is worth the sacrifice to have the greater fire power. It might be easiest to carry at the 6 O'clock position.
