This, in concert with the FN Five-Seven, may just be the perfect zombie apocalypse gun on the market. Compact, high ammunition capacity, and good accuracy at a medium range makes it perfect for urban zombie fighting. Other, longer guns will catch in doorways, and shorter guns aren't accurate enough to take the anti zombie head shot when they're close enough to be a threat, but too far for the hand gun. I love your rendition of this wonderful weapon. Much better than most photographs of the same.
I think they already have. It's the FN PS-90, a civilian semi-automatic model with a longer barrel. If you want to look it up on Wikipedia, it's in the same article as the P-90, as one of the variants.
When it comes to a zombie apocalypse? I don't really think that sort of thing would be necessary, because with slow moving zombies you could really just walk away at almost a jog and get very far from any danger. But I'd really like to know, what would be the use of that sort of thing if it doesn't use the same ammunition as the other two (which is one of the main reasons those two are considered a 'set'), and how would it be helpful in a zombie apocalypse?
Oh, I see what you mean. I don't think they're in the sniper rifle industry, just the close combat and personal defence industries. I mean, they still have the SCAR and the 2000, which are very effective in their own rights.
