I relate this loosely - having forgotten some details but ... chatting with Eric today I learned that he was recently in front of approx 90 people presenting the R9 - to the FBI!
They pretty much shot the cr*p out of what he took .. three guns IIRC including his own #2 and, the famous ''guns test/AH'' of 5,000 rounds fame.
They went way beyond what would be the normal takedown and clean ... so much so that I seem to remember Eric saying that in fact some malfunctions did occur!! Hardly surprising! After letting them cool off and be cleaned .. they wanted to still shoot more and ...... this was all GD 147's IIRC.
Long and short is - he hopes to do another presentation and .. if it all works out then just maybe .. this wonderful lil' pup could just be ''FBI approved''!! A ways to go yet of course but hey - would this be a feather in the cap or what?
I keep digits crossed for a successful outcome . If anything is right on for deep concealment, along with useful cal - it is surely the R9.
Good luck Eric with round #2!
