1. 4” GP100, stainless, full-lug, adjustable sights.
2. Another GP100, just like #1, above. I believe in the pair-and-a-spare, but with a total limit of four, well two pairs with have to do.
3. Top-tier AR15 lower. LMT, BCM, or equivalent. I can add any of several upper receivers, of course.
.223/5.56 and 6.8 SPC cover plenty of tasks.
4. Another top-tier AR15 lower, as above.
I know how to dress around a full-sized revolver, As I did when I was a non-wealthy young street cop, in the Eighties, so, can live without compact handguns. Compact handguns hurt my aging hands, when I shoot them, anyway. Being able to shoot .38 Special target wadcutters means that I can live without a rimfire firearm. Specialty .357 Mag ammo can do much, against all manner of men and beats, in places where I am likely to be, within the foreseeable future. I thought about listing two more GP100 revolvers, to complete the four. A 6” GP100 has enough sight radius to reach out and touch, if I do my part.
I can live without a shotgun. Even though my pair of M2 Benellis are my go-to home-defense firearms, that is a mission that can be accomplished with revolvers and the AR15/M4 weapon system.
I have treated this as a simple thought exercise, with no assumptions about why there is a limit of four. The outcome of the elections played NO part, whatsoever.
November being a month to be thankful, well, I am thankful that I already have more than the above-listed four firearms.
