I saw them at SHOT as well. Nice looking gun. Didn't get a lot of info, but the guy I talked with said they were made out of bar stock, so no cast frame. He also indicated a lower price than Colt but he may not have know for sure.
I hope they can produce a good product at a decent price. Always looking for an excuse to buy more guns. I would like to see Capt Baylor do a review of this and the rolling block that Tippman has out.
