I really like my Mark IV, especially how easy it is to take apart and re-assemble after cleaning. Before returning the gun to Ruger for the recent recall I rarely had a problem with failure to extract or feed, even with crappy Remington 22LR ammo. But since it came back from Ruger I have been to the range only twice, and both times had multiple failures to properly cycle. Is it me or should I be thinking of sending this gun back to Ruger?
