A long-time coworker and I were talking over coffee today, and he mentioned that he believed that Colt was still making the Single Action Army pistol, beloved of afficianados and cowboy shooters. A quick Google, and sure enough, the SAA is still being manufactured. Some more Googling, and I found that prices are sky-high on them. A fellow could pick up a couple of Vaqueros or Uberti revolvers for the price of an original Colt, 3rd generation.
Don't even ask about 1st or 2nd generation Colts. Those prices are through the roof.
