Common Beretta PX4 Storm Subcompact Problems and Solutions

Quick Overview of the Problems and Solutions
| Beretta PX4 Storm Subcompact Problems | Solutions |
| Slide Coming Off While Shooting | Refitting the takedown pin |

| Accuracy Issues | Equipping aftermarket sights |
| Jamming | Cleaning, replacing the mag, changing ammo |

1. Slide Coming Off While Shooting:
The takedown pin of the Beretta PX4 Storm Subcompact is often said to be loose by many users. This issue can be extremely dangerous if the slide entirely comes off during shooting.
This happens when after shooting a round, the slide comes back to load the next bullet into the frame. But instead, the slide can entirely come off.
Solution:
The issue here is with the takedown pin (Fig 1). The impact while shooting slowly makes the pin walk away from its position.
The solution here seems to be refitting the takedown pin on the gun. As there could be signs of wear. In such a case, you may opt for a replacement takedown pin.
2. Locked Magazines:
The issue, in this case, tends to be that the magazine frequently gets stuck after the last round is fired. The slide catch lever does not work when the mag gets stuck.
Solution:
To eject the magazines, you need to manually move the slide back just a bit, hold it, slap the mag in, and push the eject button.
You should take a closer look at the magazine. There should be a bit of wear on the part that is catching. You should polish that part with fine sandpaper. Preferably 500-1000 grit.
However, if the issue still persists, you should opt for a replacement magazine (Fig 2) from Beretta.
3. Accuracy Issues:
The Beretta PX4 Storm Subcompact is known to have accuracy issues often. Especially if the gun is brand-new out-of-the-box. It either shoots quite low or to the left. Or sometimes both.
Solution:
You may opt to get an aftermarket adjustable sight for your Beretta Px4 Storm Subcompact. As that would give your sights the capability to be adjusted by a qualified gunsmith.
4. Jamming:
The Beretta PX4 Storm Subcompact may jam due to several reasons. Such as a dirty or dry gun, an issue with the magazine, or the type and brand of ammo.
Solution:
To remedy the issue, you need to clean the gun properly. Alongside cleaning the gun, you should also need to keep it properly lubricated and oiled.
The issue can also be due to defective, worn-out, or low-quality magazines. Hence you could try to replace the magazine and see if the issue persists or not.
And finally, as a last resort, you could try to replace your ammo. Based on which caliber of gun you have, try to invest in good quality ammo to resolve the issue. As often times cheap ammo can cause several issues.
5. Failure to Feed:
Failure to feed issues may also be persistent with other types of jamming as discussed above. The solutions for jamming also apply to the “failure to feed” issue.
However, if the issue persists, there are a few other solutions provided below.
Solution:
The shooter must eliminate limp wrists altogether. As concealable weapons need every bit of force from the recoil to make the gun function properly. If the recoil is absorbed by the shooter, the gun may fail to feed properly.
And finally, if the gun is still brand new, breaking in the gun might eliminate the issue. As the springs are quite stiff on the PX4 Storm Subcompact. You could keep the slide open for a prolonged period of time to break in the spring as well.
