Right, that's exactly my point. From a perspective of gross overall mechanical comprehension, there is more going on and more to understand.
There isn't though... That was my point... I've had no problem explaining a semi auto to people, or a revolver...
Not all newbies get paralyzed with confusion, but enough do to convince me that this is a real issue. Especially if they are also still trying to cope with recoil, noise, any emotional baggage that comes along for the ride, etc. I believe those shooters are probably better served with a 4" J-Frame than with the best most reliable most amazing semi, at least for a little while until they've processed the pile of new information already in front of them.
This is where we disagree...
I definitely think we're getting away from the OP's question. Which is about new shooters, not about ideal carry guns.
I thought this was about carry guns, and a new shooter?
So to try to bring my rambling back to the question at hand: Semi or revolver for the OP's wife?
Have a conversation with *her*. Work with her on her needs and wants. That applies not just to action type, but to caliber, weight, capacity, sight radius, everything. Listen to her concerns and try to sort out what's going to work best for her, and her give plenty of freedom to change her mind along the way. Don't overload her with options or information.
Let her have her own journey of exploration. She is the only one who can make and be comfortable with her choice. Don't steer her toward or away from anything for religious reasons. If she likes the way something feels in her hands, is confident operating it, and can hit her target, what else is there to worry about?
Unless she picks something way off-the-wall crazy like a Nagant M1895, of course.
Or a Glock.....
