I had a 1911 that was too big for me to carry and I wanted something "safer". I got a M&P (I will not be trashing it here, just an example, first hand, the good kind). After I made sure it went bang
every single time, I tried holstering it with no ammo in it. I was trying to see if it would be comfortable IWB about 1:00 which is my favorite position but nothing bigger than a snubbie is comfortable there to me. Well, as I was about to point it
you know where I started to think "Hey wait a minute, what if the trigger drags on the holster or something?"
So I carry it a 3:00 now.
Point being a gun with 2
count em 2 external safeties will always be safer than a gun with one. IMVHO. At least you have to have some soft of firing grip on the 1911 before it will go bang even if the thumb safety
is off. Once I get my new 1911 CCW (that's right I said it, going from a polymer "smart gun" to an outdated antiquated pre WWI design) I plan on putting a thumb safety on it that is very very positive. That is to say that it won't just fall in to bang mode. I will feel much more safe with it than I do with any gun that has no external manual safeties.
BTW, the only reason I'm leaving the M&P at the house is that they don't make a M&P single stack short barrel 45 with 2 externaled safeties.
I'll have to get a shirt that matches my grips once I get mine for sure.
