So today I finally got my MP9c back from the gunsmith. Its been there for 6 weeks for the installation of night sights...It would have been done 3 weeks ago but something was put back together wrong underneath the rear sight. I couldn't even get the slide back on. So finally its back in and I go get it and take it to the range...it shoots beautifully. Finally my baby is home. Except now its dark and I can actually see the Tritium glow....the rear sights are glowing the wrong color. I gave them yellow rears and they put green one in. So what do I do now? I just want to make sure I didn't get an old set of rears that are going to crap out on me. It sucks because I like the gun shop that I used as an intermediate to the smith but on the other hand this smith is putting the wrong things on pistols...any advice is welcome.
