I have had more Berettas than anything else and and every one I have ever had has been absolutely top notch. They are easier to break down than most other guns, they are tough, accurate and above all very reliable. Now that is not to say you can't get one that has a problem, as with any manufacturer, but I have never had a problem with a Beretta including the PX4. Berettas come is different operating systems but the vast majority of the civilian market has the F version of each model which is a DA/SA with manual safety/de-cocker. The PX4 9mm has a 17+1 capacity, superluminova glow sights, and interchangeable backstraps to conform the gun to the shooters hand, and an accessory rail. Mine plays second fiddle to my Sig p229 for carry but it is my nightstand gun.
