3 of us NWA guys did it at the same time, $395 a piece, between the 3 of us we bought 9 guns. 3 each

At the time we just had to call glock and ask for a local distributor near our zip code. They gave us a few guys and after calling them and and asking if they did the airline pilot/Leo discount we were on our way. I had to give a copy of my ID to him and just placed my order.

That was 3-4 years ago so not sure what the deal is now but take it fwiw,

Good luck
