Damascus barrels were made of twisted steel. Hot rods were twisted around a mandrel and then hammered to make the rods into a single piece. As the age, they get very weak. Modern barrels are bored from a single piece of rod stock...
If you look carefully at the barrel, you might be able to see the twisting patter in the metal.
Don’t shoot if you’re not sure about the barrel, take it to a gunsmith to be checked out.

Good advice...I will take it to a gunsmith in any case. The safety only locks one of the triggers.
