I just bought a Hi-Standard "space gun" yesterday at a gun show. I knew what it was and really wanted it. When I got home I took a longer look at it and did some searching. Near as I can tell it is a real composite.
The parkerized frame is marked as a Flite King.The slide is steel marked Model 102 with a different serial# than the frame. The .22lr barrel is 8" with 2 barrel weights and stablizer. There is a Hi-Standard site that I'm going to contact to find out dates of the pieces.
The grips are checkered walnut target grips that I was told were Herrets, but whoever put them on spent a lot of time getting the fit right. The fit to my hand is like an extension of my arm, tho it is a mighty heavy piece of iron.
Haven't shot it yet,but I'm really looking forward to it.
