Yes I have the manual, but the pictures are lousy. In fact when they describe knocking out that pin with a dowel, they don;t show it. they actually say to remove the pin "above" the safety, but that's where they confused me. They pin is forward of the safety towards the muzzle. If I try and remove a pin above the safety, I would start taking the carrying handle apart.
I think they should rewrite it with drawings, their photos are crap.
Hmm, that's funny, because there's a picture of them doing it in my manual, in fact they show a picture of them using the allen wrench and hammer to push the dowel pin out. You might want to get on S&W's web site or call them and get a new manual.
I looked again and read the instructions, and yes, they are bad. It is the dowel pin next to the safety that you need to remove.
I think it's the same manual. See how that photo is a nice photo of an allen wrench attached to some blob at the bottom..a gun maybe..but they don't show the location of the pin. Anway I have it figured out now.
