Nice Ruger, good buy! I just bought a Mark ii Government Target model, already had two Mark iii's, a Target and a Competition Target. The Government Target looked brand new, still had the sticker and the working parts were not worn. Did a cleaning and took it to the range, nice smooth trigger and accurate, but it would fail to eject every third, or fourth time. After 20 plus rounds, it failed to extract.
Took it home, tore it completely down (didn't remove hammer, sear and trigger), cleaned it and re-assembled it. The internals were filthy, probably the worst I've ever seen. Everything looked good. Off to the range, the trigger pulls lighter, but is rough; I guess the crud made it smooth. It will not extract at all, seems the extractor just slips off.
