go with a 12 gauge, 20 gauge is too small imo.
I beg to differ.
You see, the only shotgun I have now, is a H&R Topper, Youth, 20 ga single shot.
<thread drift>
You see I was raised where a shotgun was kept behind the back door, and most often it was a Youth 20 ga single shot. The reason being, a bigger person can effectively shoot a smaller gun, where a smaller person cannot effectively shoot a bigger gun. Meaning anyone from a kid, to grandma, to parent could and did use the "back of the kitchen door" shotgun.
Another thing, that while some know, but many do not, is I was Mentored, and in turn assisted Veterans, Battered Women, Abused Kids, and the Elderly.
Again, the Youth, Single shot 20 ga was often the first gun I got a Battered Women ( and similar) up to speed with. The reason being, it is simple to operate, and the lady feels Safe in its operation. Especially if she has kid/kids.
You have to keep in mind, some of these ladies, had been beaten, shot, knifed, and in fighting, had busted fingernails, fingers, along with whatever else.
Fact of the matter is, I can and have gotten a lady up to speed in 15 minutes or less, during "serious times" with a single shot shotgun, give me 30 minutes and I will get them up to speed with a revolver.
I just turned 56 years old, and while I am no big deal, I do know for a fact, over all the years, assisting and giving private instructions, as I was mentored to do so (pass it forward) what is what.
Strategy & Tactics is the name of this sub-forum. Lee, and some others know me personally, and "of my background, and experiences".
In the instance of detached retina, and other injuries, which dictated "No Recoil" from doctors, surgeons, and physical therapists, The Marlin 60 and Rem Nylon 66 were used. Meaning back in the day, me and mine gave these ladies, and other persons mentioned earlier gun/guns to use.
How raised, what you do.
Now I have been privileged, honored, and so much more, to have these ladies recover, get over the bad situations in life, and have some fun. Teaching them to shoot skeet, and do some dove/bird hunting and again the Rem 1100 in 20 , Win 1400 were most often used. Some even felled deer using slugs.
And, I know for a fact, a lady with a Rem 1100 in 20 ga can stop a threat. And that is all I will say about that.
My point for drifting is simple: This is S&T, there is no hardware solution to a software problem,and the lady HAS to feel confident, safe, and LIKE the darn gun, whatever it is, or else they will not learn it, practice with it, use it if the time comes, nor have fun with it.
My situations were different, as I and mine did choose for ladies and the others the "tools" for persons in a bad way. Time was critical, an action had to be taken now, and matters were serious. WE keep a lot of folks from harm, or being harmed again.
Our firearms chosen, such as the single shot 20 ga, were based on some serious reasoning, and proven, and still applicable today.
