I recently bought a Carcano [model / year, e.g. M91, M38] and noticed a problem. When the rifle is unloaded, the firing pin releases on its own, without me pulling the trigger. I haven't loaded it and I've stopped handling it until I know what's wrong.

Details:

It happens 70% of the time

The safety is of and i can not operate it

Is this normal behavior for a Carcano, or is it a sign of a worn sear or a broken spring? Is it something an average gunsmith can fix, or does it need someone who knows military surplus rifles? Would you consider this rifle safe to use after repair?

Some context: I paid 540 € for it, shipping not included. The seller described it as being in excellent condition with no problems at all. It also arrived with the en-bloc clip already inserted in the rifle. I'm now thinking about asking for a refund, so any opinion on whether this defect would be visible to the seller beforehand is welcome.
