I mentioned the other day that I'd like to have an old Peacemaker of some sort someday. Here's the thing: With gun collecting, that's a completely attainable goal. A surprising number of what we refer to as "grail guns" are within reach of ordinary mortals.
Now, one would absolutely need to be a person of some means to be a serious collector of old Colt's single-actions. Even the cheapest shooter-grade First Generation SAA is gonna be a grand or two, and nice ones are priced more like cars or real estate. Enough Single Action Armies to qualify as a "collection" is gonna be getting into serious money pretty quickly.
But suppose you don't want to collect? Suppose you just want that one shooter-grade Peacemaker to take to the range every now and again, and maybe take apart and clean while you watch Lonesome Dove DVDs? A tangible link to the old frontier that you can touch and hold and call your very own? Well, that's pretty doable, then.
Old Colts, as well as Trapdoor Springfields, Spencer carbines, GI 1911s, Lugers... Stay away from the rarest variants and be willing to accept a worn finish and some mismatched serial numbers and suddenly an awful lot of really cool and historic guns fall into that price range of used motorcycle/nice entertainment system/photography hobby/Florida vacation; a price range that is attainable by most folks via a bit of judicious brown-bagging of lunches.
And unlike that used motorcycle or home entertainment system, a classic gun won't be a thoroughly-depreciated paperweight five or ten years later. A Luger or Peacemaker might not be an "investment" in the hardest fiscal sense of the term, but they at least tend to keep up with inflation (and they're a lot more fun to take to the range than a stock certificate.)
