40mm launcher/ammo improvements

[Marquesas]

I don't see a particular advantage to this, especially considering those grenades fit in a box as well. Or considering that you're unlikely to get this with a grenade kit coupled. Or considering that it's basically a massive, obvious thing that you cannot hide efficiently. Or considering that it does what using a grenade or pipe bomb in your active hand does.

Unless it makes the grenade or pipe bomb go off instantly. Hrm. That might be interesting.
