People paying $300 now would pay more for a better mouse gun
I'd like to see a .380 version of the Kel Tec 3AT / Ruger LCP, same size or a little smaller, made of a heavier and stronger metal. Titanium maybe? More mass to absorb recoil without more size. Then weaken the trigger pull (because that throws off the aim), and machine the tolerances better so it isn't picky about the ammo it is fed.
There is a big market for a top of the line, $1000 pocket gun.
