I think the current model is called the “Elite LTT”.
I like it except for the sights, silver-colored trigger, and silver-colored barrel. Obviously the sights could be changed, but is there a model with black trigger and barrel?
Also, what is the “Duty” model?
I’ve checked the Langdon, Beretta websites and a couple reviews and could not find these answers.
The Langdon M9 and Elite LTT are two different products. The Langdon M9 is exactly just that, an M9 with a few upgraded parts, and is in all black as you want. The Elite LTT is a Vertec/M9A3 slide with an M9A1 frame, and comes with the stainless steel parts.
I am almost certain that the duty model is nothing more than replacing the FO front sight with the Ameriglo Spartan set.
Thanks! What’s an “FO” sight?
Fiber Optic.
Right, I knew that, duh…thanks.
Not a fan of fiber optic sights myself. They seem even less visible than a painted white sight in lower light.
Are the optional front sights much bigger than typical fixed front m9 sight?
I handled a new Beretta in my LGS recently and had the opportunity to compare it with a Girsan regard side by side… The Girsan looked and felt better than the Beretta and $459 Canadian was half the price… I bought the Girsan. Later that week I was offered a surplus police hand in Beretta 92S in good condition for $400, I bought that as well… When shooting there is not a lot between them although the Girsan has better sights and grips… The Girsan has an anodised finish that I don’t see wearing out. Just thought I would mention it
