For the money, on paper, the Staccato P looks hard to beat. The only other close competitor in the price range is the yet to be released Dan Wesson DWX. For a double stack 2011 in the $2K price range, there are not a whole lot of other options, and even less if you want something with decent quality.
As for NightHawk, I own/love their single stack .45 1911 design. Not so sure about their 2011 doublestack 9mm pistols like the TRS. This design is a new adventure for them, and for $4500, I want to be sure it is rock solid and problem free. I'm also not too keen on the looks of the NightHawk 2011 looks either. Very plain and industrial looking. Almost like a prototype pistol that is unfinished.
