I got three quotes for a Glock 19. Blue Ridge in Chantilly($550), Virginia Arms in Manassas($535) and Guns & Ammo in Manassas($529) in Manassas. Topglock.com sells one for $460 + $18 shipping. Are there cheaper places to buy a Glock 19? Has anyone tried to have the local gun shops match online price? How about gun shows? What was the going price at Chantilly national gun show or Dale City Old Dominion gun show? Thanks in advance for any help.
