I just purchase a G19 for $399, extra mags (limit 6) @ $19.00 and Glock holster for $9.00 direct from Glock. If you're Active Duty, or retired military, you're eligible for the IOP (Individual Officer Pricing) program. My price was representative of the general discount throughout their entire catalog. It even beats the GSSF pricing. You can see their pricing at Eds Public Safety http://www.edspublicsafety.com/glockindividual.html
or I dealt directly with Customer Service at Glock and had them ship to our Rod and Gun Club on base who had an FFL on file.
Hope this helps somebody
