But when they day comes that they can incorporate the USW design into Glocks and SIGs like they did with the CZ based Sphinx pistol, then you will have something. Right now my smallest PDW (not counting my VZ-61 Skorpion) it a B&T TP9 SBR. It's a tad expensive but it actually works and you don't have to solve reciprocating slide problems.
