1-2-3 Drill: A Simple Training Exercise to Improve Accuracy and Target Transitions

Effective self-defense requires more than simply owning the right equipment—it requires consistent training and skill development. One practical way to build essential shooting skills is the 1-2-3 Drill, a straightforward exercise designed to improve target transitions, follow-up shots, and overall accuracy when using a less-lethal launcher such as the Byrna CL Launcher or the Byrna CL‑XL Launcher.

This drill combines several fundamental skills into a single training routine, helping users develop better control, efficiency, and confidence with their self-defense tools.

How to Set Up the 1-2-3 Drill

Setting up the drill is simple and can be done in a safe training environment using appropriate targets.

Begin by placing three targets at a distance where consistent hits can be made comfortably. For beginners, it is recommended to keep the targets relatively close together. As skill improves, the distance between targets can be increased to add difficulty and further challenge accuracy and control.

The drill works especially well when using a seven-round magazine, which is available for the Byrna CL and CL-XL platforms. Load the magazine with six rounds to complete the drill.

For added realism, the drill should start from the same position where the launcher is typically carried—whether from a holster or an off-body carry option such as a bag or backpack.

Executing the Drill

The sequence of the drill is simple and easy to remember:

Engage the left target with one round.
Transition to the center target and fire two rounds.
Move to the right target and fire three rounds.

This sequence—one shot, two shots, three shots—is where the drill gets its name.

Key Tips for Success

A few important fundamentals can significantly improve performance during the drill:

Maintain a consistent grip. The grip should remain steady without resetting during transitions.
Focus on smooth transitions. Moving too quickly often leads to overshooting the target and losing valuable time correcting the aim.
Prioritize accuracy first. Speed should only increase after consistent, accurate hits are achieved.

Why Drills Like This Matter

Training drills such as the 1-2-3 Drill help reinforce muscle memory and improve situational readiness. Practicing target transitions and controlled follow-up shots prepares users to respond more effectively under pressure.

Consistent training builds familiarity and confidence with less-lethal tools, ensuring that if a critical moment arises, the skills needed to respond are already in place.
