Great find, I have an odd story to tell of finding a gun while metal detecting, it was during a club hunt, Eureka club out of Denver, CO , but the annual coin hunt in the forest took place in Leadville , CO , Well , the gun went off ( to start the 45 minute all you can find hunt) people swinging detectors like crazy and digging shallow because the coins were only a few inches deep. Everyone kept walking over the same piece of pipe saw it was metal and went on because we only had 45 minutes and they were all coins or tokens buried about 2-3 inches deep. Everyone but one who just had to find out what it was everyone was passing on. It turned out to be the barrel of a revolver , i think an old colt. Its been so many years I can't remember, but the man brought it back all cleaned up the next year while the rest of us kicked ourselves for not be curious enough during the hunt to bother with a piece of pipe.
