The OP has a special kinda situation going on, part of it is age-related...
because the body does get old & less tolerant of stuff as we get into the
Twilight Years (55+), stuff just hurts more. Arthritis is a mean SOB.
Part of it is GAS, Gear Acquisition Syndrome...he wants other stuff to play with.
I'm currently contemplating selling off part of my S&W pistol collection to help pay for a newer RV.
So the decision he is going through is a familiar one...and not easy at all.
Draggin my feet like heck about actually putting 'em on a gun sales site...
unless I hit the Lottery, it's probably going to have to happen fairly soon.
