Well I went in trying to put a XDM Compact 9mm since I already had a XDM full size. Well the guy saw my fire department hat and told me about Glocks program for the LEO/military/fire service. So I went with the $435 price tag versuses the $599 price tag. Not a hard choice. Don't have it yet it needs to be ordered so soon. I can buy a lot of stuff for what I saved and Glocks are good guns.
