I own a couple of each save the SVI.
All are great pistols. Baer's are known for outstanding accuracy, a hard fit barrel and not being finished/polished to the degree that a WC or a Nighthawk is. There's a reason for that. A Baer will run you about $1K less than a WC or an NHC.
The WC's and NHC's that I have...you can't tell em apart. Both are fit as slick as possible in a 1911. Both are accurate as all hell...as accurate as the 3 Baer's I have.
You can't go wrong with any of the 3. It's all about your budget. Since you don't have one...the best thing you can do is try to find one of each to fondle. Probably tough to do but that's the best advice I can offer.
Or you say screw it and buy one of each. If you're like most of us....that's where you'll end up anyway. LOL!!!
i love SVI....but I have an STI tactical 5" 2011 on me right now....I may be the odd man out. STI is the choice for a double stack 1911 but I would prefer Wilson Combat in the single stack category. If allowed a third option, I would recommend Luke Volkmann over all of them.
I've owned a number of Wilson's over the years and their ULCC 9mm is my primary carry weapon. I also have their EDC X9L, which replaced my SpecOps 9. Never had an issue. Reliability and accuracy are excellent. Builds aren't as fancy as some STI offers, but I like plain and functional.
