new member here - lots of great info so far. I have a brand new SR9, about 60 rounds through it, and would like to remove the striker to clean it and maybe remove the mag disconnect. It looks pretty greasy and gritty. I've followed the videos here and at Ruger.com, and have the striker as far forward as they say, with the mag disconnect and the striker blocker button depressed, but the striker cover won't come out when I depress the cover release button. It looks like the striker is still "protruding" into the cover and not letting it slide out. Any suggestions, or has anyone seen this before?
