This guide will show potential reasons why is your Sig P320 shooting low and things you can try to shoot more accurately. 

  • Trigger finger curling
  • Poor grip
  • Anticipating recoil + downward jerking motion prior to the bullet leaving the barrel
  • Unzeroed sights (Included red dot)
  • Wrist down
  • Bad ammo (More apparent for long distance shots)

The Sig Sauer P320 is a pretty accurate gun whether you have the full size or compact length barrel. For the most part, a pistol shooting low is mostly caused by anticipating recoil on top of other poor fundamentals.

The shooter can diagnose their problems use this pistol error chart below:

To go one step further, please try the MANTIS X10 tracker to EXACTLY diagnose errors with much more precision.

Simply, just mount it on the accessory rail and then connect to your smart phone or tablet via blutooth. One of the feature on the app is recoil tracking and shot error analyzer. They can track the muzzle movement in real time to provide the shooter helpful feedback.

See more on what this app can do for you below.

Readjust Your Grip First

A proper grip can fix most shooting errors. A proper shooting grip should include:

  • Grip high on the gun
  • Close all void inside the grip (Proper fit in your hand)
  • No death grip
  • Pull with support hand & slightly push with shooting hand
  • Relaxes trigger finger
  • Good shooting stance

Poor Sight Picture Alignment

Poor sight picture alignment maybe the problem with iron sights. This is pretty common with new shooters.

Mitigate Recoil Anticipation

Recoil anticipation is the biggest cause of a missing shot like we have mentioned above. Any downward jerking motion before the bullet leaves the barrel will cause the pistol to shoot low.

Another reasons could be Uncoordinated follow up shot cadence.

Adding a muzzle brake won't immediately fix the problem, but it can help mitigate muzzle flip once the fundamentals are put in place.

Squeeze The Trigger Independently

The stock Sig P320 is a decent trigger. It's not too stiff or too light. 

If your shot hits low or low left is due to squeezing and curling your whole hand while pulling the trigger instead of moving your trigger finger independently.

As target distance increases, this will impact accuracy significantly.

*Tip: Get to the wall of the trigger first, then slowly squeeze to the rear until the trigger breaks. If the shots tend to go to the left, it generally means too much finger on the trigger or uncoordinated trigger squeeze. 

Re-Zero Sights Correctly


Be sure to re-zero the dot, test and verify point of impact. Don't let an un-zeroed sight skew your accuracy.

If you're shooting with a red dot sight, the dot will give you immediately feedback on how much the muzzle is tremoring or shifting before you send a round down range.

If the shooter jerk, it will be very obvious.
