I actually bought a standard Brig in Nov 2014, as I was trying to resist the extra $ of the Wilson Brig. I also wanted a Brig since they had bee out of production for so many years... I did a few mods to it, and even had night sights installed.
But after seeing the pics of the Wilson Brigs on all the forums, I finally gave in and bought one last summer. I couldn't resist. I am not a huge fan of the grips they came with (I just recently changed mine). But damn, if those green Wilson grips don't look super sweet.
I've shot a 92A1, and I own a Wilson/Beretta 92 Brigadier Tactical. As shipwreck noted, I feel the recoil impulse is a little more subdued on the brigadier slide, and I'm glad I bought the Wilson version I did. If there had been an Inox version, I probably would have gone with that, though I do find the black finish more attractive.
Shipwreck, I have to say, I don't quite understand all the aspects of your feelings about target acquisition being faster with a rounded slide versus a more squared off slide. The last time I saw your notes about this I pulled out my Brig Tac and my 1911 and compared the two. I didn't really feel that there was any increase in speed when acquiring the front site on a rounded slide, versus a squared off slide. But, I know you have been shooting for a lot longer than I, and you have been shooting 92 variants a lot, so your speed and experience probably makes this difference a lot more noticeable than mine does.
Is it just the contrast of shapes (rounded slide and square post on a 92 or 1911, versus square post on top of squared off slide with a Brig)? If so, do you find guns like Glocks and XDm's, and other square on square sight picture type guns slower to acquire the front sight as well?
Well, on a 1911... The top of the slide is rounded. Then, you have the front sight... I pick up on the front sight so fast because of the curve of the slide below the sight. And, on a 1911, I can actually just cover the target with the front sight and shoot a bullseye at 7 yards or less... Without even lining up the rear sight to the front sight. The fact that the front sight stands out so well makes this easy to do, and rather fast.
A slide with a squared slide (like a Glock), doesn't have the front sight stand out quite as much. At least in my opinion (although, I have had some aftermarket Glock sights that are taller than factory sights, and this helps minimize this issue).
For me - on a standard Beretta slide (or on a Vertec type of slide, like the M9A3 comes with)... The front sight is taller, AND it also sticks out more noticeably from the slide because the slide is curved below the sight. The front sight on the Brig is actually shorter on its own. And then it sits on a squared off base.
I can bring the gun up and on target, with the front sight covering what I want to shoot, faster with the non Brig slide. That front sight just pops more and stands out more IMHO. Shifting from target to target, I am faster with the non Brig slide.
Now, I haven't timed myself shooting both to make it official. But, the front sight pops up in my brain faster.
I am very, very particular on my sights. I have friends that tease me about this all the time. I hate buying a new gun where the paint on the sights are messed up, even in the least. I also hate seeing new guns with trijicon night sights, and the white paint around the tritium is already screwed up. I won't buy such a gun.
I also see tons of screwups on the paint on the sights on CZ handguns. This annoys the hell outta me when I view the sight picture on such a gun.
So, maybe I am more particular about handgun sights than others.
