I'm 5'8" @ 175 lbs and I carried a alloy frame 1911 Commander for a while with no issues at all. It is still my go-to semi auto CCW though my FN HP is a close second and gaining. A Gov't would be a bit more of a challenge, but I'm confident I could carry one OWB at 4 o'clock with no problems.

IMO the 1911 is still the pinnacle of semi auto pistol design, and I've been shooting for 30 years and owned a lot of guns. Despite being a cheaper brand, mine has been brilliant, meanwhile I've had other guns, including Glocks, that were utter garbage. Saint John was a god-dang genius.
