Dry fire
Dry firing firearms is the practice of discharging (or simulating the discharge of) a firearm without any live ammunition, or practicing with an inert laser/infrared training platform such as an iMarksman or SIRT (Shot Indicating Resetting Trigger) training pistol, and may also include the use of a target/feedback system, such as the iDryfire or LASR software.
Grip, drawing, sight alignment, trigger control, reloads, troubleshooting malfunctions, and more can be trained during dry fire practice.
The technique allows people to conduct a safe, economical form of training to improve their shooting skills.
[2][better source needed] In recent years, a number of companies have developed methods of enhancing dry fire practice to improve skills.
These include chamber inserts available for various caliber firearms, as well as dedicated training pistols or replacement AR-15 bolt carrier groups.
There are also a number of target systems for these laser dry fire training aides, that are becoming more affordable and popular.
Compound bows are particularly susceptible to damage due to high tension and numerous moving parts.
It is generally considered acceptable to dry fire more modern centerfire firearms without a cartridge or snap cap for limited volume training.
These two laser beams are supplied by SIRT in combination red/red or red/green respectively, and on the red/green variant the color mapping can be changed by the user with a button.
[22] The pulse duration of the laser is measured in milliseconds (ms), and is important for correct detection by target or camera systems.
[23] With purely electromechanical dryfire cartridges the duration of the pulse is often mechanically controlled by the firing pin and typically lies around 100 ms, while some other systems have digitally controlled pulses that are shorter, for example 60 ms[24] or 1 ms.[25] These may be required for camera or target systems to be able to correctly detect single shots, and stands in contrast to laser systems that emit a continuous laser beam as long as the trigger is held, such as the SIRT 110.
