True about the 1911s, but CaneI was asking for personal experiences and preferences, the way I understood it. I tried to carry my Rock Island 1911 .45ACP milspec, but it was even heavier than the CZ75BD. I could carry the CZ75BD - and did, for about a month, every day - but eventually chose not to. The Rock Island was too heavy for my to comfortably carry...
There are soldiers who carry M60 crew-operated machine guns, but I certainly am too old and too weak to do that! I did carry an M16A1 when I was in the U.S. Army Infantry, 1975-78.
CZ75B all day everyday in a Comptac CTAC.
Questions like this one come up all the time, but consider that loads of people carry 1911's all the time with no problems.
