Though definitely not an expert but do have some experience in its use in military and law enforcement. Have carried one for approximately 25 years before changing, in rotation, to a Glock 22 and a Sig 226, with no regrets. The 1911 is an excellent personal defense weapon if one can cope with the size and weight. For law enforcement use, too big, too heavy and too few rounds. Now a civilian in retirement, when out in public, I rotate between a Browning Hi-Power and a Glock 19 and don't feel the less unprotected. My current 1911's of two down from a high of eight, I only carry on my property and feel no need to carry one out in public with its physical discomforts.
