I am having a problem with my slide. It is gritty sliding the slide to the back so that I can cock and then pull trigger so that I can disassemble the weapon. The problem is the trigger will not operate so that I can disassemble it. I know that I have to take the striker cover off so that I can remove the striker cover and the striker so that I can then separate the slide from the assembly. It seems like I have to lock the slide back and push with a 1/16th punch in the small hole and then the cover is suppose to come off....only problem is that does not work....any suggestion would be welcomed....I am hesitant to mail the gun to Ruger as it is almost 2 hours to the closest FedEx that accepts pistols. Thanks in advance....Paul
