It is only opinion and you know what they say about opinion. What makes this guy the gun fighting expert; how many did he survive; what was his evolution in carry guns? When he answers these questions, we might be open to discussion. I agree with you on the 1911 and quality baby 1911 such as your Mustang and my government model .380 but a carry gun is sometimes dictated by circumstances and mission. If I want to leave little trace of my passing, I would use a revolver and do carry them on a daily basis. If I am headed for the big city, my 1911 and a S&W 642 accompany me.
For vehicle ConcealCarry, I pack a 45 with laser sight.
Also like to pocket carry a nice little Ruger 380 which is easily “not visible” on person.
Yeah, I know all the low power arguments against 380, but it’ll do the job up close and personal and considering most wanting to hold you up or assault do not really look forward to getting double tapped, even with a 380.
I agree with your post.....opinions. Everyone has them and everyone can agree or disagree. I’ve carried daily for years and still do not consider myself a professional. The key is....carry what is comfortable to you!! Carry different pistols/revolvers as needed. Carry multiple items as needed. 45’s...380’s....doesn’t matter considering having any gun is better than not having a gun at all! Get plenty of range time and shoot with the ammo that you will be carrying. Try different carry ammo and buy quality ammo! Buy quality holsters the first time and carry what is comfortable and safe for you!
But...all that is just my opinion! Personal example...at work...discreet carry pants...S&W Bodyguard .380 chambered with Hornady Critical Defense ammo...holstered in Alabama Holster Company right pocket holster...extra mag in Alabama Holster Company pocket single mag holster in left pocket. Most any other time...Glock 30 chambered with Hornady Crit Def ammo...holstered in Comp-Tac Minotaur IWB holster/right strong side carry...two extra mags in Comp-Tac dual belt slide holster on left side. It’s a win/win on any occasion! Too bad all my holsters, ammo and firearms were lost in a tragic boating accident....sad day!
