I fell a couple of times last week ,it's hell on a gun. Rock put small bent in barrel on outside. Used it 3 times total 9 shots. Cleaning gun to go out today and the barrel looks like there is a crack in the barrel not a dent on the inside. Is it possible to crack a barrel or if it's chrome lined could the chrome be cracking or flaking. I'm wondering who I could send it to,to check. I did't believe barrels were made of hardden steel? Anyone have opinion?
