I finally got a chance to handle a Beretta APX and an FN 509. To say the least I was not impressed with the 509 at all, just seemed like an FNS with a thicker slide, different grip texture, and the same old gritty trigger. Between that and the compact size slide and barrel sitting atop a full-size grip reminds me of why I got rid of both of my FNS-9's a while back. They just really didn't do anything for me, which is why I tried two separate pistols.
The APX on the other hand, I will just say that Beretta needs to hurry up and make that in a compact model! The grip reminded me a lot of my CZ 100, that being very ergonomic and comfortable, as were the unorthodox, yet effective slide serrations. The slide itself is blocky, and maybe it was just the model I was looking at, but the trigger reset was very faint, almost like how bad the earlier M&P's were. The trigger pull itself however, was very nice with minimal take up slack and a nice, crisp break.
Still need to get my hands on a P10 C. Maybe one of these years? [emoji23]
