    Range and power isn't so important for a pistol. Smaller and less recoil means more shots and better control.
     
    [X] 8x19 mm Palten Armée Pistole

    At short range, less recoil and possibly a bit more stopping power and magazine space. At long range, bullet drop is predictable and can be made up for with sights, while wind drift isn't. I think.
     
    [X] 8x19 mm Palten Armée Pistole

    No difference between the two is as big as being able to fit 9 rounds of 8mm into the (vertical) space that 8 rounds of 7.63 take. That's a single stack too, if we decide to take the Navy at their word and go with a double stack, we can get something less likely to be unusable by smaller Akitsukuni hands.
     
    Can we get the terminal ballistics hack from last time on the case here? :p

    Damn, this is hard. I'm guessing the Army would prefer the longer range of 7.63x25 mm Katzen, but the Navy might like more powerful shots, as well. On the other hand, the Navy would like the low recoil of 8x19 mm Palten Armée Pistole since they'd probably be using it more (assuming they still do boarding actions!), and the Army might like having more bullets on tap...

    In the end, I'm going to go with the one I know saw 20+ more years of service in the real world. Heck, maybe we can turn them into 7.62x25 Gaya-Tokarev bullets later on!

    [x] 7.63x25 mm KKatzen

    Because neither of these rounds is particularly potent alone, I want something we can push harder with better barrels.
     
    [X] 8x19 mm Palten Armée Pistole

    I'd really like to go double stack, and this would be thinner to facilitate that and get more rounds in when we do.

    We might also be able to go simple blowback with this.

    Also if we tie again, do we just make a pistol that fires both? :p
     
    [X] 7.63x25 mm Katzen

    I should note that the IRL evolution of this round, the 7.62x25 Tokarev, can beat light vests that would stop other pistol rounds like 9mm. Might be worth testing how much door or wall this can shoot through as part of our pitch to the Navy?

    The Army wants a bigger bullet, and the Navy wants more rounds per magazine. The 8 does both of those. I honestly don't get how this is even a question.
     
    In case we ever get a request that allows something that ridiculous, I'm sort of wondering.
    What changes would the American 180 have to go to in order to fire .22 spitfire or hornet instead of .22 lr?

    Click to expand...
    Click to shrink...
    Well, for one it would have to be upscaled to accommodate a cartridge twice as long as LR. The firing pin would have to be switched for one that is compatible with centerfire cartridges. That's all just for .22 Hornet.

    I'm sure someone more knowledgeable about guns can elaborate on further complications.
