I was a big supporter early on of the PPX but now I may wait until they roll out a compact model(for better concealed carry) or they are more available in CONUS.
The PPX hits all the marks for defense/duty sidearms(hammer fired DA only, ambi controls, easy to strip/clean, good sights) but Walther is not a common brand. Holsters, gear, magazines, parts are always a hassle,
.
The price is right for a PPX($400-500.00 USD) but I may wait until 2014 or so.
