I waited a few years after the PX- 4 came out to get one in the sub compact model and love it .. one of the smoothest stock triggers I have shot .. its my present carry .. it's in 9mm and am thinking on one in 40 .. a caliber I also like .. and which my other carry a S&W Compact is in ..

I kind of like the look of the large serrations on the APX .. I haven't seen or handled one in person .. I believe they were released this week .. Will be going to the large box gun store tomorrow and will look for one ..

A few things I like is ---
5-6 pound trigger pull
Flat trigger
10/15/17 round magazine in 9mm with a 20 round extend magazine available .. 15 rounds for the 40 ..
inter-changeable frames but doesn't list the frame sizes and whether there will be a sub-compact model ..
