I hate living in Colorado with our 15 rd mag limit. I'd buy this in a heartbeat otherwise.

Even with the $28 shipping this price blows any other deals out of the water! This isn't a basic model with "luminescent" sights, it's the L.E. with real tritium sights. Super deal, in for one in a couple days. Hope your deal lasts til then!
