Here is another thing to make you go "hmmmmm."
Rohrbaugh got federal approval to build and market an "R-9."  Whether the gun has sights or not was really neither here nor there to the feds.
However, when Rohrbaugh started shipping guns with slides engraved "R-9s," the feds suggested they stop since they were only licensed for an "R-9."  Thus was created a small number of very collectable guns that say "R-9s" on the slide.
Don't you feel safer now?
