Nope... silly as it may seem, something like that could get you literally shot by a cop or someone with a concealed handgun license but not enough restraint.
Camera stocks were very popular in the late 40's and through the 50's, especially for movie cameras. My Dad used to go moose hunting with some friends in Canada back in the 50's. One of his friends had a stock for his B&H 16mm camera. Canadian customs confiscated it, stating it looked like a stock for a handgun, which was illegal in Canada. Just shows, looks and impression are more important than fact and function, then and now.
