Wow, you have excellent taste; and you're more of a high end gun slut than I am.
I thought I had a problem because of buying a Nighthawk Talon and a P7M8. It's always nice to know there is someone with it worse.
The Vickers Tactical is simply awesome; the whole thing about the plunger tube being a part of the frame always struck me as really cool. I had one come unstaked once on a S&W 1911 -- very, very annoying. Can't happen on the tactical. The solid trigger is a nice touch, too though I don't care for the red dot. Good, solid dehorning like all of the Nighthawks. All around they're excellent guns. I saw a fellow at the range the other day with one. Owning a Nighthawk is kind of like a owning an unusual car or motorcycle or something -- you can spot another one a mile away and you always have something to chat with they guy about.
I go the other way than
Tony on the Wilson v. Nighthawk debate (not surprising, given that I bought the Nighthawk). The comparable Wilson gun (to the Talon) is the CQB.
The checkering on the Nighthawks is superior, and hand done, while the CQB is machine checkered. And IIRC, the CQB doesn't have the back of the slide checkered (which is useless, anyway, but looks pretty cool). Also, the CQB (at least on paper) comes with a sub-4lb. trigger. I'm not really into that for a carry gun.
I only have two complaints about the Talon. First, like every other all steel 1911, it's too damn heavy. Sure, I still carry it, but I complain about the weight. I'm debating having them build me a titanium lower for it so I can use the steel for the range and competition, with the titanium for carry. Second, the PermaKote on the safety has chipped off in two tiny spots. I'll send it back to them for a fix up when I have time. Not a big deal, but annoying.
I can't say much about the Valtro, simply because everyone has said it better than I can. One of the top 1911s in the world. I know it sounds stupid, but the Swenson guns have always had an elegance to them; I'm not sure why, but they do. Smooth flowing lines and functionality all rolled into one. Jardine has whatever it is that Swenson had that allowed him to get that "look" that everyone loves about the guns. Something about the 1998 just makes me want to paw it.
