After looking again at the schematic at Numrich I realized that I still need the ejector tube guide. The missing part doesn't affect function so after some more work on the ejector I did some shooting today. All ammo tried grouped decent but 6" low at 10 yards. Everything from Aguila Colibri to CCI Stingers hit pretty much the same place. Don't really want to alter the front sight so it will stay that way for now.
