It appears that I don't fall into either category. I suppose I'd call myself a "shooter-opportunist-upgrader", meaning that I have particular guns to fill a real need, be it hunting, self-defense, home-defense or just something that pleases me to shoot for fun.
If I find a good deal on something that doesn't particularly fill a "need", I often buy it to use as trade-bait, or equity, toward an upgrade. Once I've upgraded a certain revolver, pistol, rifle or shotgun, I usually sell or trade the lesser of the breed.
I only have a few guns that I purchased way back when I was still young, like a gorgeous K-22 Masterpiece (1947 vintage) that I use on squirrels when shotgunning, and a beautifully blued and polished Ruger M77 Bicentennial (1976 buy) in .270, that I use for distance shooting on deer. I sold an Erma .22 Luger look-alike and a Colt New Frontier .22 and replaced them with the K-22. The Ruger replaced a Savage 110 in 7mm Rem. Mag. Just upgrading. There are some that I wish I still had (HK 91, AR-180, 2 S&W 28s, S&W 49, American Eagle Luger, Savage 29B, Mossberg 144 Target, and many more...), but they didn't fit the need at various times.
So... not a collector and not an accumulator. Kinda like the old kid's game "What Am I?"
