Well after a year and half I finally finished building my 1919a4. It was a bigger challenge then I expected and the fact I couldn't screw up any of the parts made it a little nerve racking. I had to do a bunch of machining and learn to parkerize so I could finish her up. Need a couple of fasteners and a trip to the range to sort it out but I'm pretty proud of this build.

Yes it's a little smaller then a standard 1919a4. It's a Lakeside 1/2 scale kit that I found on another board. It shoots 22lr and can run belts or links which are in the little ammo cans. Seeing how they haven't made these kits in years with zero parts available if you screw one up, no directions and not much in the way of help online it made it a pretty daunting task.
