Double Deuce, while I would not buy such a rare caliber, I would keep searching for the ammo & see if I could get it at some decent price. I would not get rid of it by any means. Who knows, you may come across a cache from an old gun dealer, etc.
If you can get ammo, it might be a nice plinking gun & use the .38 for normal SD.
Remember the American heroes of Flight 93.
