I actually have some experience training people with "hand out" guns
There was a rash of break ins and robberies and drug shootings a few years back at my college in Southern Indiana back when the whole opoid crisis made a perfect storm with the high level of meth down there.
I had 3 of my friends call me and ask "I need to get a gun what do I do" and I walked them through getting a cheap Chinese knock off pump gun, and then took them to my gun club and gave them a half days instruction. I already shot skeet with 2 of them and 1 of them had been hunting so they new the basics.
The biggest things I found being an issue were recoil control and manipulation. With proper body position/stance and even a basic use of firearms getting hits was not an issue even with shooting from the hip. Though giving them snap caps really was useful in getting them trained up in manipulation as well as teaching them push pull and to lean into the gun to control recoil
Something else I did to help teach them to defend themselves and their homes was force on force with airsoft guns teaching them what the angles would be in their house from the door and from the bedroom and to figure out what is the best place to get cover and concealment, as well as to help teach basic weapons handling/close in marksmanship. I didn't teach them to run around like rambo, but if someone was trying to kick in the door where was the best place to post up with a clear shot to the door and concealment/cover, and also the best place to cover the door from the bedroom.
I really do think airsoft is an under-rated tool here to teach people safe weapons handling, manipulation, and basic force on force.
Something I did that was really helpful in this situation and would be helpful if your serious about hand-out guns it to do some firearms instruction, even if only volunteer. I did some work helping a friend set up and instruct some intro to handgun classes, and I also got the materials and did the coursework on being a NRA Personal Defense in the home but I never did get the cert.
Just having that experience was huge in being able to my friends trained up. And honestly with how much the guys here at LFer know about firearms and whatnot it would not be a bad idea to even volunteer as an instructor to gain the skills in how to teach and disseminate knowledge about shooting and the 2nd amendment
2 places you can volunteer to help out train people is 1. Students for Concealed Carry at your local College. Im sure the local president would be happy to have you take some people out to the range or give a presentation. 2 The collegiate shooting sports initiative. It would be a great place to get some young pro 2nd A college students out and teach them how to be safe and use a gun and then get them out to shoot USPSA or two gun. It would be a great way to give back, learn how to train people, and also ensure that the younger generation still protects the 2nd Amendment-
