Conversation re: buying/selling illegal items isn't, in and of itself, illegal in the USA (yet). It is, however, against forum policies. The end result is the same.
That said, it is ABSOLUTELY not illegal to discuss the mechanism itself, and I have schematics for various forms of DIAS for G17/19/26 guns, varying in levels of sophistication, etc. Feel free to discuss the mechanism itself.
