ithaca model 37 deerslayer 12 ga, for PARTS or REPAIR, first shot will fire, then action locks up. bore and over all gun looks to be in good condition, 2 3/4 & 3 inch shells, front fiber optic sights.
Looking at a model 37 that is cheap. Any ideas on what the problem might be?

Hell, for the price I could just use the barrel on my other 37...
