I have known three different people through the years that lost fingers to an exploding damascus shotgun barrel.
One gun was an old Belgan made beater, and it should have been enough just by looking at it to make you gun-shy about shooting it when it was brand new.
Another one was a very nice old Parker trap gun, that was by all outward appearance, about as good as it gets.
When they let go, it is almost always right under where you have your left hand on the forend.
To me, it is just not worth the risk.
I have plenty of other shotguns that simply are not going to let go and blow my fingers off.
