A friend of mine has an older Contender frame (one with the cross bolt in the hammer) and three barrels that he has purchased at different time. He has shot all three barrels on this frame. The other day he went to the range and found that two of the barrels would not lobk up , allowing the hammer to fall completely, but the 22 LR barrel would , as always. Does this sound like a problem with the locking lugs not matching with the frame or another problem with the frame ? As I mentioned, all three barrels were fired on this frame before. Need your help.
