I'm a handgun instructor and teach CCW/CHP (Concealed Handgun Permit in Colorado) classes. The 1911 is NOT the recommended gun for inexperienced shooters and those starting out for Concealed Carry. For me, the PROs of the 1911 are
1. familiarity and proficiency - I've been shooting the 1911 for 45 years with many of those years competitively. I know the gun, it "fits" me and I'm proficient with it.
2. Trigger - in my opinion, there is no better handgun trigger than John Browning's design in the 1911
Cons for those starting out
1. Single action only - although this is a PRO for me - the same trigger pull every time
2. less capacity - standard single stack magazine
3. Manual safety means 1 more movement to ingrain
4. Condition 1 carry (cocked and locked) freaks people out
I have a range bag of "try" guns I use to introduce new shooters into the easiest handguns to get started with, including some inexpensive starter guns that I've wrung out to prove to myself that they are reliable.
SCCY CPX-1 and CPX-2
Taurus PT111 G2
Taurus PT24
Smith & Wesson M&P Shield
Glock 19
Many new shooters end up choosing Glocks. They work well for them, are easy to learn and are reliable and accurate. Personally, I throw up a little every time I put one in my hand
but that's just me.
The hardest obstacle to overcome for me trying to teach most women shooters is to find a gun that comfortably fits smaller hands, and has a recoil spring/action that they can easily manipulate.
