I think that price includes 200 rounds of ammo. That's probably an $800 value right there, LOL!
Too bad they didn't make it for the 50AE. I doubt there is that much difference in ballistics, and having a proven source of brass and ammo would make it more marketable.
If this takes off, Glock will probably introduce a 50 GAP double stack for small hands that still can't use it :-D :-D
