Dry fire
Dry firing is weapons training without launching a projectile.
Dry firing is the practice of operating the trigger mechanism of a bow, crossbow, firearm, airgun, or other ranged weapon without firing a projectile. In archery, this is often called dry loosing, and it involves releasing a drawn bow or crossbow without an arrow or bolt nocked. This is strongly discouraged because the elastic energy normally transferred to the projectile is instead absorbed by the weapon itself, which can cause serious structural damage. The term also applies to any training or tactical simulation that does not use live ammunition.
Dry firing is most common with firearms. It can be done by cocking an unloaded gun and pulling the trigger to release the sear. However, it is advisable to cushion the firing pin’s strike with a dummy round, a snap cap, or an empty spent cartridge casing. Interactive dry fire methods exist, such as using a laser pointer or infrared light training platform like a SIRT training pistol, often paired with a target feedback system or software.
The main purpose of dry firing is weapons training, especially to practice form and trigger control for better accuracy in shooting sports, or to troubleshoot firearm malfunctions. Gunsmiths also use it to test the action of customized or accurized guns. Dry firing is safer than live fire, helps build muscle memory for trigger control without developing a flinch from recoil anticipation, and allows practice in places where live ammunition is not legal or practical, such as at home. It can train grip, drawing, sight alignment, reloads, and malfunction clearance. It is also cheap, since live ammunition is a consumable expense.
In recent years, companies have developed products to enhance dry fire practice. Laser-emitting chamber inserts for various calibers, dedicated training pistols, and replacement AR-15 bolt carrier groups are popular. Affordable target systems for these laser aids provide feedback on shot placement and timing, making practice more effective and enjoyable. Training cards with drills also help shooters build skills that transfer to live fire.
In archery, dry firing can be hazardous to the weapon. Without the projectile’s mass to absorb the released elastic energy, the energy dissipates through vibration of the bowstring and limbs, potentially causing significant structural damage.

Lore & Background
Dry firing is most commonly performed with firearms by cocking an unloaded gun and actuating the trigger to release the sear. It is recommended to cushion the firing pin strike with a dummy round, snap cap, or spent cartridge casing. Interactive dry firing methods use laser or infrared light platforms such as the SIRT (Shot Indicating Resetting Trigger) training pistol, often paired with target feedback systems like LASR software. In archery, dry firing a modern high-energy compound bow can cause cracked limbs, bent axles, string derailment, cam warpage, string or cable failure, cable slide failure, or even cause the bow to shatter. Crossbows, with higher draw weights, are even more likely to be damaged. While some bows survive a dry fire with no apparent damage, manufacturers typically do not warrant their bows for dry firing, and any dry-fired bow must be thoroughly inspected before shooting again.
Reader's Guide
The primary purpose of dry firing is weapons training, particularly to practice form and trigger pull kinematics for better precision in shooting sports, as well as troubleshooting firearm malfunctions. Dry firing is safer than live fire, helps condition muscle memory of trigger control without developing a flinch (a pre-emptive reflex from anticipating recoil or trigger weight), and allows practice in locations where live ammunition cannot be used legally or practically. Grip, drawing, sight alignment, trigger control, reloads, and malfunction drills can all be trained. In recent years, companies have developed laser-based dry fire aids—chamber inserts, dedicated training pistols, replacement AR-15 bolt carrier groups—and target systems that provide feedback on shot placement and times. Training cards offer structured drills. For firearms, dry firing is generally acceptable for limited volume training with modern centerfire designs, though older designs such as the CZ 52 and Colt Single Action Army are exceptions. Rimfire guns pose a risk because the firing pin is designed to impact the cartridge rim; dry firing an empty chamber can damage the pin or breech face. Precautions such as snap caps are recommended for rimfire weapons.
Did You Know?
- Dry firing an archery bow can cause cracked limbs, bent axles, cam warpage, or even shatter the bow.
- Some laser dry fire systems use a combination of red and green lasers, with the color mapping changeable by the user.
- The SIRT 110 has a take-up laser that lights as long as the trigger is pressed past the reset point, and a shot indicator laser that lights after the trigger is fully triggered.
