There's no doubt in my mind that a 1911 takes more practice to learn to use properly than a Glock. As a Marine who joined after Vietnam, I liked 1911s, but I didn't like M-16 A1s(the newer ARs are ok..
). I've owned several 1911s over the years. I don't own one now because of neck surgery, so I carry something lighter but I miss carrying and shooting a 1911.
I also agree that most civilians when dealing with a Law Enforcement Officer, carrying a "cocked and locked" 1911 get nervous. And nervous/scared people sometimes do stupid or unsafe things. It's best to avoid making civilians nervous whenever possible.
I remember eating at a Whataburger in Grapevine(Texas) late at night(many moons ago) and seeing a Grapevine Police Officer carrying a 1911 and how my fellow patrons reacted to seeing the 1911 with the hammer back. It didn't bother me but then again I'm not a typical civilian...
I think a 1911 is a great firearm in the right hands and in the right environment. I have known several law enforcement officers over the years and had several that were my martial arts students. None of the officers I knew carried 1911s but some of them told me that their SWAT teams did.
I've dealt with violent people as an armed security guard, bodyguard, mental health associate, and never had to shoot anyone thank God. I was always able to talk someone down or physically restrain them or get them to leave the property without the situation escalating further.
I believe a firearm is just a tool and the verbal deescalation and physical skills are even more important than which firearm is on your hip(unless your serving warrants on violent felons, etc., etc. and yes I know anyone can get violent...that's why it's best to do your best to keep it from getting that way as much as possible, when possible.).
