I do not work for NFA, but as far as I know, Glock has still not released a date or ETA for the Gen 4 19.
I do know for a fact, that Cliff has been in contact with the regional sales manager in this region about getting a more steady, plentiful supply of Glocks. Also, I believe NFA is at the top of the Gen 4 19 list. They have about 14,000(ok, make a LITTLE less) people banging down the down the door asking for one. I have not been in there once without hearing that question!!!!
