The thing about the 915 is not necessarily finding one, but to find one in pristine condition. The blue/black 3rd Gen pistols show every little scratch and ding, especially the alloy frame. And, like a member wrote in an earlier post, they were an economy model and bought to be use. From the 915 pistols I've seen on consignment out here in Southern California, that sure seems to be true.
Great find, OP.
