I'm looking to get a backup pistol/off duty pistol here soon. There's a place about 2 hours from my house that gives a Police/Military Discount on Glocks. I can get a Glock of my choice for $398. Comes with Pistol, 2 mags and a case. I'll want night sights on there, so that'll be another $50. I don't know much about pricing...so is $450 good for a new Glock with night sights? Or should I be looking for a better deal?
