I had a Kimber Ultra Carry II in stainless,,,,3 inch barrel and never had a hitch,,,,was a joy to carry,,,,7 round mag with one in back pocket,,,,went to a WC Commander which was 8 +1,,,,also carried well although heavier.
I personally found the 1911 frame to be very easy to conceal and with a GOOD holster and belt wearable all day long.
Changed to the Glock 19 15 +1 with this one,,,,although I do miss the 1911 once in a while.
I found less in the mag and one in my back pocket was more comfortable. You may also find that many rounds on your side will get heavy as the day goes along and the less with a backup mag, flat like the 1911's make it much easier,,,,I also like a backup mag in case something goes wrong with the installed mag....
Best of luck in your search.
