I question whether this pistol is Mathilda's 1911
this right here is Mathilda's 1911 paintball pistol, note that the grips are different, the trigger guard is different, and that the image above does not look very much like a 1911.
exhibit 2
red arrow points to Ruger SP101, Green Arrow points to the automatic pistol that is contested as Mathilda's 1911 and the blue arrow points to what I think is actually Mathilda's 1911
