This 2011 was built by the Master Pistol Smith that built all the STI Guns before he retired. Everything on this gun is the same or better quality than a modern Stacatto. Had a 2 pound trigger all atlas springs, ported Island barrel, SIGs premier RDS, Grip Safety Pinned, so much more and shoots and returns to Zero like an Atlas. Over 4k invested asking 3k OBO.
