I've told myself "I'm done" and I am. Since the "Newtown incident" and the aftermath acrimony, I have acquired a 2" 34-1, a 4" 64 tapered bbl, a 4" 29-2 in nickel only because I actually like making a "deal" with Khalid the local "wizard of the arms bazaar", and a Colt 6920 because CDNN had a 1 day sale that created an "on my table" price of $815. I'm really done.
I like JSRIII's comment about focus. I once saw a display of Browning P35's (HiPowers) with 140 variants. I told the owner "Must be nice to have all of them." He replied: "Not even close."
Another time a gent had a single Colt SAA in a fancy display case with tons of accouterments( this was at least 25 years ago so I don't remember any of the story). He told me he traded his entire collection for it. I asked why would he do that. He said it would appreciate in value faster than the other guns, it was easier to tote to shows,and he kept it in a safe deposit box at the bank allowing him to sleep easier.
So I guess focus is really the issue whatever we do. Joe
