Picked up a 629-1 w/ 8 3/8 barrel . the previous owner tried to mount a scope on the barrel rib and crushed ribs on the top in 4 places , about a 1/4" to 3/8' circles . doesn't hurt the gun , just looks like hell . Do I replace the barrel , or is there any way to fix ? Can take a pic when I get home . How do I get another barrel ? Send it in ? any help would be great . thanks
