Well, just because the gun can do it to 100 and 200 yards, the shooter that can do that with a handgun is few and far between. The PX4 is a fine gun, one of the major plus factors is the ability to have a CX4 that uses the same mags, great for IDPA and IPSC. There are several different versions of it IIRC like DA only, SA/DA, safe action (perhaps more).
Telling you the truth I compared one side by side with a Glock 17 (as I was looking for 9mm). Others may and will probably tell you differently (as opinions are like a**holes, everyone has one) but when the PX4 was $1025.00 and the Glock was $650.00 I went with the Glock. I never owned a Glock before. I really had no interest in the Glock, but... Honestly I was leaning HEAVILY towards the PX4 simply because of the CX4 thing, but now that I can get an AR lower for Glock 9mm magazines, I think I will be just as happy building one of those.
I guess it is really up to what you like best. Beretta is EXCELLENT quality usually. The few PX4's I have handled all felt really nice. It felt like a solid gun. These standard ones with the Black barrels look better to me then having that little bit of silver sticking out of the front. If you are getting a good deal, like I said the new one I looked at a couple days ago in Toronto was $1025.00, then go for it.
