I went into a gun shop last week they had 3 686s, a 6 inch, 4 inch and a 2 1/2 inch. The 6 and 4 inch barrels were 699, the 2 1/2 was 750. I knew this was just a pricing mistake so i asked the clerk, why more for the shorter barrel than the longer ones. His reply was i thought stupid. 6 and 4 inch barrels are aboundant, but 2 1/2 inchers are not that common. My question is, is this guy full of it or what ? surley it cost more to make a longer barrel ? am i wrong ? your thoughts.
