maybe, maybe not. I assumed that a product used to clean/shine/protect other synthetic materials, that adding another application to it's already broad list might have been a point of interest. If it was not used in the (not that these pistols were suffering from lack of shine) photographs, I just suggested it, and repeat a variation of the warning from the bottle of Armour All: Don't apply to control surfaces.

Although it wouldn't matter for a temporary photoshoot, (aside from achieving a dazzling shine) the grip and slide serrations would be quite slippery for normal use.
