I am unable to view that due to my slow connection so I have no idea what those guns are.
When I was growing up just about every farm had two guns. A .22 rifle and a 12 gauge shotgun. Some also had a handgun, usually a .38 special.
Daddy had an old Essex single barrel. It was a cheap gun but was surprisingly easy to hit with. He did have a high quality .22. It was a Remington 513 targemaster and it really did shoot with great accuracy.
Daddy brought 3 handguns home from WWII including a Luger but by the time I was old enough to remember them, he had sold them all.
A person can get by just fine with the .22 rifle and a shotgun.
