I am not the seller, but you can tell it's not the brigadier just by looking at the slide.
In my self proclaimed expert opinion it looks like the Centurion Tactical, which has a shorter slide and barrel.
It's also built on the "G" model, the safety lever is only a decocker. It was built for the French Gendarme contract, that specified only a decocker not a safety. I have one of these, and it's just BUTTER!!!!!!!!!!!!
