Overdeveloping Your Index

Published on April 22, 2026
Duration: 6:06

This video from Achilles Heel Tactical focuses on 'overdeveloping your index' through a precision shooting drill. The instructor emphasizes drawing the firearm and stopping it on a small, 1-inch black paster with a target reaction time of 0.8 seconds. The goal is to build extreme precision in the draw stroke and sight alignment, enabling faster and more accurate shots when a larger target like an A-zone is presented. The drill pushes shooters to their limits to enhance hand speed and efficiency, even if it means not achieving a perfect 'stop dot' at faster speeds.

Quick Summary

Overdeveloping your firearm index involves training to stop your draw on small, precise targets like a 1-inch black paster. The goal is to build extreme accuracy in your firearm's natural resting point, enabling you to shoot sooner and more effectively on larger targets. A key metric is achieving a 'stop dot' on target within a challenging reaction time, such as 0.8 seconds.

Frequently Asked Questions

What is the primary goal of 'overdeveloping your index' in firearm training?

The primary goal is to build extreme precision in your firearm's index point (where it naturally comes to rest when drawn). By training on small targets, you force a higher level of accuracy and control, enabling you to shoot sooner and more effectively when presented with larger targets.

What is a 'stop dot' in the context of this firearm drill?

A 'stop dot' refers to the moment the firearm's sights are perfectly aligned with the point of aim on the target at the exact instant of firing. Achieving a stop dot on a small target indicates a high level of precision in your draw and sight alignment.

What is the recommended starting point for reaction time in this precision index drill?

The recommended starting point for this drill is to aim for a reaction time of approximately 0.8 seconds to achieve a stop dot on a 1-inch black paster. This time allows for deliberate precision while still pushing your capabilities.

How does training on small targets benefit shooting at larger targets like an A-zone?

Training on small targets like 1-inch pasters forces you to develop a highly precise index. This heightened precision means that when you transition to a larger target like an A-zone, you can acquire your sight picture and fire much sooner and more accurately because your firearm is already indexed so precisely.
