I am in the market for a glock 30.. I have called about 15 gunstores in the chicagoland area and none have any used. One dealer is asking $540 for brand new and $560 out the door with fixed sights. My other alternative would be going to a gunshow which is about an hour and a half away. Should I make the drive or is this a decent deal for a brand new glock? THANKS FOR YOUR HELP!!!!!!!!!! btw......What are the pros , cons between new and used?
