In my last concealed handgun class, a former marine took nearly 45 seconds to draw and fire from his H&K USP40. He couldn't get it off the safety. But you are correct, I recommend a handgun with little to no levers and other safety devices to manipulate and lots of training. In a stressful situation, the most basic of training should kick in BUT if one hasn't practiced 1,000s of times, their basic training may not save their hide.1911 is a wonderful handgun, but in my opinion somebody not particularly comfortable with guns would be better off with a Glock. Much less to think about in a stressful situation, just pull the trigger and keep pulling it until the bad guy stops moving. Heard too many stories of people failing to hit grip safety etc. on 1911's to suggest them to a newb. Not to mention, depending on the condition you carry/hold the firearm in, a newb might shoot themself.
I used to compete in pin matches with a modified Colt 1911 frame running a 38 super. I need to get back into reloading and build another 38 super.
