Note: aliengear holsters have an exchange policy for the formed shells for the pistol. If you have any other pistol, you can return the shell and receive any other shell they carry in exchange. (Free). I use thier holster.
I think it will, you can call them up and ask them . I have the 2.0, and I got this in a trade but beeing in south Florida its to hot for a this one so I ordered something with a small footprint. I know that between 1.0 and 2.0 there are no size changes.
