I have a Silencer, and three Signatures, I like the interlocking takedown system, but I do not like the gtips.
If you can find someone that has a Silencer with near perfect decals, they can take a good digital picture and e-mail it to you. With this, you can have replacement decals made. One of the members here, Al ? is a good source for decals, but I don't know if he woul dhave those.
Bowdoc and Rich can tell you where to get a pin for the Serial numbers and nominclature.
