Again, more very good discussion points. I love it. This Forum never fails to make me happy to be here. It's the good people.
On that other forum, I never trashed semi's and I never said that revolvers were better than semi's for everyone. I pointed out the differences, as well as why, most often, a revolver for newer people, or those who will not practice enough, would more likely be a better choice. But it was the attitude of that CCW instructor that really pushed my buttons.
One of the posts above; "Just remember: The Colt 1911 served many years and in many places reliably!"
SO TRUE!
But again, the original 1911 was designed for the military, and for use by soldiers, who were given training. Plus,, during it's service,, soldiers were mostly male. The military categorized the 1911 as a secondary, back-up firearm & not a primary weapon. And yes, they taught the malfunction drills too. Thrown in the type of ammo, and the 1911 was very reliable in general. But combat is a different scenario than daily carry. We could spend volumes discussing the 1911 in general.
But that CCW instructor was all about the 9mm according to the poster there.
Now, so far, I've avoided stating what I carry much of the time when I carry a daily firearm. I do carry daily, and depending upon where I'm going, it can depend upon how I dress, and what I might encounter, or the event or places I'm going. Like I told that OP poster over there, "It's ok to own more than one firearm & more than one type."
Most often, I carry a Kimber Ultra Compact 1911 in .45 acp. My reasons; (1) I've spend decades with a 1911 in practice, and competition with a 1911. (2) I can handle it right or left handed. (3) I've practiced my grip to where an accidental mag drop hasn't happened in many, many years. (4) I know how to handle jams, malfunctions while under stress & with speed. (5) I can rack the slide one handed if necessary. (6) The .45 acp round is well known as a very capable man stopper. (7) It's easy & comfortable to wear & not too heavy. And my fun reason #8, If I do get into an armed confrontation, and my gun gets confiscated until courts clear me, it won't be one of my beloved Rugers!

But I also sometimes carry a LCP in a pocket, or slip on a Blackhawk onto a belt holster, or tuck a full sized 1911 in my belt, or grab a Security-Six or GP-100 & tuck it into my belt. I haven't handled my LCR enough yet to feel 100% comfortable with it FOR ME. The gun has been just fine, it's ME that makes that choice.
Again, as so many here have understood, there is nothing wrong with semi's in general. But to totally dismiss a revolver, when you are an instructor, AND while in many scenarios a revolver could be superior to a semi, is just wrong.
