You want fun then get something comped while you're doing this, whatever you choose.
If you don't have a size limit, go with a big comp as well, like 3 top ports with a side port on each side, really keep things flat.
Both my P320s have twin port comps, I don't consider going back, not even to the single port, and I conceal carry these. Springer Precision has a 3 top port with twin side port comp for them, may buy one just to mess around with, though it'll add a good chunk of length that'll kill carry-ability.
Anyway, they're quick, flat, they make things easier, mine are absolutely reliable with the DPM recoil systems, I actually run the heaviest springs in them.
So, whether you go 2011, CZ, or striker, think about running a big compensator to bring the fun and enjoyment up.
