Frequently Asked Questions

Why might my Glock be shooting low left?

A common reason for a Glock shooting low left is shooter flinching, particularly for right-handed individuals who unconsciously pull the trigger. It can also be due to the rear sight being improperly adjusted, often indicating a previous attempt to compensate for this flinch.

How do I adjust the rear sight on a Glock to fix low left shots?

To correct low left shots on a Glock, you need to move the rear sight to the right. This adjustment compensates for the point of impact being left of your aim. Make small adjustments and test fire after each change.

What is flinching and how does it affect shooting accuracy?

Flinching is an involuntary tightening of muscles, especially the hand and arm, as the trigger is pulled. This sudden movement disrupts the firearm's aim, causing shots to deviate from the intended point of impact, often resulting in low left or low right groups.
