As far as I know, those Nightmare models are very new to the market. I have not seen a lot of them around. I would expect to pay above average price, probably MSRP or more, considering that they are so new to the market. They look like a great gun though.
between sig and colt?? ill take colt any day of the week. sig is ok when it comes to the P22x series of guns but im not terribly impressed by their 1911 offering.
just my opinion
