HK USP .45 Full vs Compact

[filetitan]

Hello,

Would anyone know what the size difference is between the two? I currently own the compact model and I am looking into buying the below holster. Wasn't sure if it would be a good fit if used for the compact.

I use Forbus for my Kimber 1911 and love the holster.

Thanks!
