Yes, I bought a Beretta 96D Brigadier stainless slide, followed by a stainless 96 Elite barrel. They are currently being treated with melonite. I will eventually find a 96G-SD frame, convert it to DAO, and mate it with the top end. This will be the 3rd Beretta I have built this way.
I have done it with Smiths, but the Beretta 92/96 series has a strong following that loves to mix and match uppers and lowers to create something special. I see it a lot with Sigs as well.
