I recently picked up a used Beretta PX4 full size. Have not shot it yet, but now ive seen they have the APX. Im curious on how the grip feels between the 2. I'll doubt I'll run across an APX to hold for awhile. Judging by the pics, the APX looks a little more streamline and ergonomic than the Px4. I kinda do like small grips. Plus the APX looks like it has a way shorter trigger pull. I've come across them for $350 ish new and wouldn't picking one up.
