This ain't in CO, it's in Oklahoma City. I recently visited a place called H&H Gun Range, and it's the biggest damn gun shop I've ever been to! Looks like they'd have pretty much anything you need/want, and they have some nice looking shooting lanes too. And a cafe! Ain't making any pos or neg claims about the place, it's just freakin' huge and well-stocked. If you're ever in OKC, stop by and check the place out. Just east of I-40 and Meridian, close to the airport. http://hhshootingsports.com/Gun_shop.htm
