Hello, new to the forum. I was pleased to read how well members treat newbie questions, so here's mine:
I just acquired a Ruger P90, and have gone through the user manual, successfully disassembled and reassembled the gun, and am looking forward to firing it.
However, there's a "lever-looking" part on the gun's right side, at the top of the grip, adjacent to the slide. The manual only identifies the parts on the left side of the gun, and I don't see that part in the blow-up parts diagram. There's no mention of a safety in the manual, though this looks like it could be one, except for it's being far from the trigger action, and it doesn't move. The right side of the gun is shown in the attachment.
So, what is it? Could it be an appendix left over from the 1911? Surely not, but I would like to know its function. I'm surprised the manual doesn't mention it, but I also had to resort to YouTube to get the slide to release--the manual wasn't clear enough for me.
Thank you, and I look forward to many enjoyable sessions with this Forum.
It seems from the parts-breakdown displays, that it's the "grab it and pull it out" end of the hammer pivot pin (the axle upon which the hammer pivots).
If the slide had been removed, and also the right-side grip, you could pull this pin out, and the gun's hammer and mainspring would fly up, out, and under the nearest couch, never to be seen again.
Or something like that.
