For anyone planning or even considering purchasing a Glock google GSSF Discount. I believe they have changed the rules somewhat, but basically you pay something like $35 a year but get a fairly hefty discount on any handgun. GSSF is also a CMP affiliate and there are other assorted benefits.
Definitely a great way to pick up a Glock for a nice price! Also, if you are law enforcement, military, EMT, fire fighter, and I believe the discount also is extended to those with a commercial pilot's license now as well, Glock has great factory direct discount prices as well. Shoot me a PM if you need more info on that!
