I searched and got nothing. I would like to hear from PX4 9mm owners. Please tell me what you like, what you dont like andis it reliable? Would you recommend it? Trust youre life to it?

I don't own one but people that do have only good things to say from the post that I have read. Beretta makes a good product period.

for the price range that it is in, it competes well with the other guns in that range, glock, m&p and xd. That being said, I sold my PX4 when I traded up for a H&K P30. If I get another gun in that range, i'd probably go with the glock or m&p because of the reliability, comfortability (is that even a word?) and amount of things you can do to them. I'd like to send one to bowietactical and just tell them to go nuts.

I have a few friends that work in the neighboring county that are issued the .40 version... and they love the gun.

So, when I was looking for a .45, I picked the PX4. Softest shooting .45 I've ever shot, and is pretty accurate. Never had any issues with it, and was completely cera-plated (Trijicons, Stealth controls, and a Bedair guide rod were also added).

Last year, I began looking for a new range gun. Wanted a Glock 34, but NJ only allows the 10 round magazines. The 9mm PX4 also has a capacity of 17 rounds, but Beretta makes a NJ compliant magazine that holds 15. Picked it up used from a member on BerettaForum, and it is at CCR for similar treatment as what was done to my .45 (only has Trijicons and an EFK extended barrel).

The only thing I don't like is that Beretta doesn't push the gun that much. The PX4 came out a year prior to the M&P, yet look at the aftermarket the M&P has compared to the PX4. There has been interest in CT to make a set of laser grips for the PX4, yet it isn't moving that far. Blackhawk putting out a Serpa for it was a nice addition, but I just don't see aftermarket companies investing time into a gun that Beretta really doesn't advertize (compared to other companies). With the Compact coming out, maybe there might be some more interest...

My biggest complaint of the platform is that Beretta has not put a .357 SIG version (just a .40 with a different barrel), and that they are not planning to put a .45 version of the Compact or S/C. I'm not getting rid of my PX4s anytime soon, but I don't see myself buying another Beretta pistol unless they put out something smaller in .45.

I just handled one at a local store and it seems to be very comfortable to handle, but just like the OP, you just don't see much information on them.  Was looking at an old issue of American Handgunner and they had an article on the PX4.  Let's just say there wasn't much fanfare written on it, at least not compared to the length of articles that are usually written.

I love mine. It shoots great, very accurate, and feels better in my hand than a Glock/XD/M&P. I would take my PX4 over any other DA/SA gun in the same price range.

I had a .40 and LOVED it
I got rid of it ONLY because i was buying holsters and mag pouches for my 2 glocks
and i decided i just needed to consolidate on the glock as my sidearm (plus the obligatory 1911)
So i sold it for another glock.

It was accurate as a pistol can be, reliable, ergonomic. great great pistol. I would still recommend it

I think beretta is alot like Colt, the military contract became 1st priority and they lost touch with the civilian market.

I bought one for my dad in 2007, he loves it.  I've only shot it a few times but it seems to be a great pistol just like my other Beretta's.

I have shot two of the 9 mm models (both the DA/SA trigger, is it the "A" trigger, or the "F" trigger?). I like the feel of the gun, the recoil impulse and the ergonomics a lot.

I really don't like the way the triggers worked in the ones I shot - in SA mode the take-up from reset is very long compared to a Glock or my CZ. It's more like the H&K USP trigger, or dare I say it, much like the one on my Ruger P89.

ETA: IMO it's too fat to carry concealed, but they're really reliable, so I have no problem trusting it if it were there.

Own a PX4 in .40 and have nothing bad to say. Good gun, shoots well, very managable recoil. Don't know if that has anything to do with that rotating barrel but it is a cool concept. Breaks down easy for cleaning too. I would buy one in a minute

Beretta is a bit out of tune with the civilian market IMO.  Most folks are going to a striker-fired, polymer frame gun with no slide-mounted controls –– aka Glocks and clones like XD and M&P.   The aftermarket is a good barometer of this.
