One of my favorite pistols is my Wilson Combat Brigadier Tactical 92G. Mine has a fantastic trigger job by Ernest, as well as a Wilson Combat frame dehorn and Armor Tuff refinish. It is an excellent pistol, and I had the opportunity to shoot it at a Langdon Tactical class.
My recommendation? Buy the LTT Elite with the trigger job. As good as the Brigadier Tactical is, it doesn't come with the factory dehorn, and to me, that's a huge upgrade if you ever plan to take a 2-3 day class. The hot spots on the 92 were annoying enough to me to go through the trouble and expense of sending the pistol back to Wilson Combat for their dehorn. The LTT model has that baked in. This is also a feature that I suspect took quite a bit longer to implement than the rest of the spec sheet - and I think it truly separates the LTT Elite from other factory 92s.
Another reason is holster selection - while these days there are more holsters available for the Brigadier Tactical, the LTT model looks like it should be compatible with just about any M9A1 holster thanks to the Vertec slide profile.
Bottom line, as much as I love the Brigadier Tactical, right now I can't see spending more money for one over a new LTT Elite.
