my px4 shoots low.
 
I bought a px4 full size in 9mm a while back and after about 1000 rounds it still shoots low. Some of my reloads do better but still group about 5 inches low. Other than this I love the pistol. Has anyone else had this issue?

Was that from a vise or solid rest?

If you are shooting low groups, change your sight picture till your groups are higher.

Almost all my shooting is done with sandbags across the hood of my jeep. Pretty solid rest. I've thought about filing the front sight a little. Could that work?

Once you have the gun hitting your target, you have the sight picture required to make your gun work. Don't file on your gun, work mentally with whatever sight picture is correct.

I never look to purchase a handgun with adjustable sights, I prefer simple fixed sights. I learn to shoot each gun and make mental adjustments.

That's what I'd do. Five inches off is too much even at 25 yards. I'd also see if shorter replacements are available from beretta.

What sight picture are you using? Is the black of the target sitting on top of the front post like a lollipop or is the top if the front sight in the middle of the bullseye (x-ring) in a center of target hold? What distance to the target? Some guns are set up for different sight pictures. I found most of my US made guns were set up for a 6 o'clock hold while my Sig is set up for a dead center hold at 25 yds. Hits at shorter distances are usually a little lower than at 25 yds. My match 1911 is set up for a 6 o'clock hold to put rounds in the x-ring at 50 yds.

If your gun is continuing to hit low with your preferred sight picture, and if it has dovetailed front sights, you can find out what height your front sight is and order a shorter one from Brownells or Midway, or other gun parts outfit.

You could also try a heavier bullet. Counterintuitively, at closer ranges, heavier bullets tend to shoot a bit higher. I don't know if it's entirely true (yes, it's hearsay on my part), but I've been told that a lot of Euro pistols are engineered to shoot the 124 gr ammo.
Before you start buying files and new sights, if you're using 115s, try 124s (or 124s to 147s). It might save you a bit of trouble.

If it continues, try this: http://www.berettausa.com/products/px4-series-adjustable-rear-sight-and-front-sight/e00457/
I stuck an adj rear on my CZ, couldn't be happier.

It is true that you won't know until you try. But in a given handgun caliber a heavier bullet is often lower velocity, then it hits lower.

Thank you everyone. I think I may try to find a shorter front or adjustable rear sight.that sounds like the best option to me. I don't want to have one pistol that I have to aim different than the rest. Just want to pick it up and go
