Almost any FFL will do a transfer for you for a few dollars; typically twenty bucks or so.
Find one near your home and set it up. They'll provide you with a copy of the FFL to forward to the seller, who can ship direct to the FFL.
I can't imagine why firearms companies would want or need to give a discount to a pilot. Some do have first responder discounts that apply to fire, law enforcement, etc. Glock did have a program that included pilots; I don't know if it's still available.
Then again, you can get some very reliable firearms, and some excellent deals these days, with lightly used firearms like some police trade-ins, saving a couple hundred dollars. AIM and Recoil and such places offer them (I've bought a few); hard to beat.
