At my age (almost 73), downsizing is often on my mind. I'm considering selling off a few more handguns, ones that I hardly ever shoot and/or don't like to shoot and getting down to six, a number I consider absolutely minimal and essential. Living in a two story house, I feel having two loaded and available guns, one on each level, is essential. (I used to keep only one in my bedroom, in a small GunVault, as my only home defense gun. One day while in my "work room", which is the furnace room as well on the lower level, I heard a noise which I mistakenly thought might be a break-in. It suddenly occurred to me that there was a large distance between me and my gun, and decided I needed to be better prepared for the future. Now I have a second secured GunVault with a loaded semi-auto in this location.) I also have two concealed carry guns, so if one ever needs repairs or is otherwise unavailable, I still have a gun that I can easily carry. Then there is my favorite target gun, a 10 round S&W 617 revolver in 22LR. And number six is the only gun I own that has sentimental value, a beautiful S&W Model 19, 4-inch, nickel, 357 Magnum revolver.
I'm not there yet, to my basic six. But I find that as I get older I do want to simplify my life, including not having to stock as many different calibers of handgun ammunition. I also would like to downsize my house, but right now my wife is still determined that we keep this large house as a gathering place for my entire family with five grown children, spouses, and soon to be 11th grandchild. So my downsizing is pretty much kept to my guns and my clothes (I've gotten rid of almost all my suits, and haven't worn a tie but twice, for weddings, in the almost three years since I retired!)
