I don't feel like playing. The 3 gun meme
JayG asks " I'm assuming that this is a "forever" type question, as in there's been a law passed that we are only able to own one of the three types for defense. "
For selecting carry handguns. Lots of folks likes them some variety, and I'm not the best shot, of all the pistols I've tried, with my 1911, and a 1911 is certainly not the smallest, and the whole cocked and locked thing is a personal worry I need to overcome, and there are rough bits that can dig into you when you do carry it, and it's kinda heavy... But. If restricted to just one handgun, I'd select the 1911 and get used to my problems with it and never look back. Why? It covers everything I'd want a handgun for and it's strengths overcome the minor weaknesses. When used by me.
Ok, I'll play, you convinced me. I'd choose my rifle, my shotgun, and my pistol. There! You happy? Fulton M1A, Remington Model 11 12g, Springfield Loaded 1911.
If just one, I'd choose my rifle. If just 2 and I was mobile, rifle and pistol. If just 2 and hunkered down, rifle and shotgun.
