Remington may feel the need to show owners how to clean their firing pin for some reason. We never felt it necessary, so no instructions included with an R9. The issue with some of our loose firing pins is that when we were assembling them, they had to be tapped in slightly, however, some were very easily dropped in. In our test firing of those firearms, there did not seem to be an issue with them, although, some did decide to turn slightly in the slide and cause malfunctions (jamming). We took care of those R9s straight away when they came back to our shop for the issue. There were slightly more than a handful of them eventually that came back, and every one was remedied by using a thicker firing pin retainer from a different batch of parts. Of course, because of the internet, it seemed like every R9 was an issue with firing pin retainers. . . . a statement that is quite untrue. . . . . but, as everyone knows: "I read it on the Internet, so it must be true." lol
