I wanted something for a more ,"urban" environment. After looking around I decided to try the Beretta CX4 9mm.

This one utilizes the PX4 mags. I have 17 and 20 rounders.

I installed a Vortex Strikefire, green or red dot + a 2x magnifier.

Function; I fired ~400 rounds Saturday, all mixed, from 115gr. to 147gr., flat point, hp, mil ball etc.
Not a single hitch, nada. All brass landed in a 2' circle at about 5 o'clock.

Trigger is a little long but, very repeatable and smooth.

I didn't even attempt accuracy testing and all shots, for all loads, landed in a 3-4" area, at 50 yd.

A lot of plastic, yes.
A smooth action, yes.
A lot of fun, yes.

I took a good lock at both my home locations and decided that 9mm, from a 16" barrel, made sense, for me.

YMMV.
