I am looking for some information on adjustable rear sights for the PX4. I have one with fixed sights but the gun shoots low and left.. At this time neither the front or rear sight will move. A local gunsmith has tried moving the sights to no avail. At this point I am looking to remove the fixed rear sight and replace with an adjustable one. I have searched many sites online and called various manufactures of sights but no one can tell me who is making a replaceable adjustable rear sight.. Any help would be appreciated
Also any help on breaking free the fixed sights from their dovetails would be helpful.

Both your front and rear sights go on (direction wise) and off the same way.
Opposite than most guns: As you shoot, looking down sights, they come off to your < LEFT-off, and go on to your > RIGHT-on.
As far as "adjustable" rear sights, 3 dot, you might try Night Sites out of Las Vegas..
I know my rear 3-dots, by them, night sights, white/glow-orange, have a small, center, set screw, for any minor adjustments left or right, but that's it, for my Px4 40.
Also, IIRC, over in the Beretta Forum, same question was asked and, IIRC, something was said that Trijicon had them, or was in the process of making them for the Px4's.

Are you sure it's the gun? I've never heard this complaint from any other PX4 owners.
Perhaps you are jerking or squeezing the gun when you fire.......??????

Gun has been bench fired so I don't believe it's me...but who knows I use a glock for a carry weapon and have no problem with trigger squeeze but still getting used to the Beretta pull. Also the groups are consistant even with single action. I have ordered a p500 sight pusher so hopefully that will help with breaking the sights free..but so far can't find an adjustable sight. Also called Trijicon and nothing available at this time.

Can you see any deviation of the sights from the central plane of the gun? When I bought my PPS the rear sight was a millimeter or two off from the central plane and it shot about two inches to the left on it's first range trip. Perhaps this is the problem (although I'd be willing to bet you have already checked that).
I wish you the best of luck. The Px4 is an awesome gun. I love mine.

C919 you are correct there is a slight deviation of the rear sight. I am sure that is the cause of the left shooting but the 3 inch low groups is what concerns me. I am sure when I can get the sights to break free I can correct right/left groups. Not sure what to do with the low groups.

Not being rude, but Beretta sights generally need to be ON/over the intended POA target, as opposed to most that *sit just below or mid-level of said target.
*Like my Sigs or SA, for example.
May work, may not, but just a thought, as not all guns sight the same way.
Sigs, SA, need to be lower than my Beretta Px4 for the same POA/POI target groups.

Yup, my Beretta front site likes to be "on top" of the target more than my other handguns.

Went back to the range and tested some new loads. With gun benched and 3 dot aligned have to hold at 12 to get groups in the bull... Guess at this point I have to wait for someone to make an adjustable rear sight...or eliminate the 3 dots and file down the front sight.

I have also had a lot of problems shooting my PX4 storm .40 caliber. My dad and I tried to move the sight but it wouldn't budge. I was always shooting low and to the left as well. I was so frustrated I almost traded it because I looked all over (even on beretta's site) for adjustable sights. For some reason, I finally got a hit. You can order them from beretta:
