A young man came to our local shoot in Clovis last month. He had a new Engraved Pietta SA. He fired 2 rounds and it jammed. The cylinder base pin had moved forward. Easy fix I thought. After this happened twice, I checked the base pin, the grooves for the cylinder latch to contact, were only on one side. I don't know if this is normal or a manufacturing error. I told him to order a 3rd Gen Colt pin and be done with it. Time will tell. Are all Pietta SA's this way.
