Hi all I'm new to the fourm . Started owning and shooting about 3 years ago. So I removed the safty from my m&p 9c2.0 9 mill . I got the plugs from smith and wesson yesterday. So after removing the sear housing block and installing the plugs . I. Realized that the L shaped plug that goes into the right side of the frame extends into the frame too far. There is like a little shelf that the plug stops on top of . It's that little shelf that the sear block wedges in between. The plug extends past it ever so slightly but its enough to stop the housing from going in.
I have watched videos where they say they have had the same problem but if you mess with it a bit you'll get it? I don't see how ? The plugg extends into the space the sear housing has to occupy. I called smith and wesson they said they didn't know why . They said mabey the plugs you got are some how defective borax out of spec. They are sending me new ones.
Could I just trim the plug a bit with a exacto knife or a piece of sand paper?
