NLT’s Dry Fire Training Pistol: Overview
Take Your Pistolcraft to the Next Level with the SIRT Dry Fire Training Pistol 
While NLT knows that dry fire training is no substitute for live fire training, neither is there a need to rely on it exclusively thanks to the Shot Indicating Resetting Trigger (SIRT) Training Pistol and the exclusive laser feedback mechanism. Designed to complement, not replace, live fire training, the SIRT Dry Fire Training Pistol brings together a host of patent pending technologies critical to improving shooting accuracy while addressing issues of cost and liability.
Safe, effective, and innovative, the SIRT Dry Fire Training Pistol was developed by shooters for shooters. We understand the unique training demands and restrictions faced by today’s law enforcement professionals.
Built tough with sturdy steel construction, the SIRT Dry Fire Training Pistol looks and feels like the real thing by matching the size, weight, and center of gravity of the officer’s live fire pistol. In addition, the SIRT Dry Fire Training Pistol even offers a host of customizable features including mag cartridge changes and replaceable sights.
Unlike a standard live fire or Air Soft pistol, the SIRT Dry Fire Training Pistol provides instantaneous performance feedback and no need for ongoing expenditures such as ammo and targets through laser feedback. Because of its flexibility and cost-effectiveness, the SIRT doesn’t just permit additional training — it encourages it.
Simple to use, the SIRT Dry Fire Training Pistol is applicable to a range of training exercises including shooting accuracy, sidearm handling, integrated cardio and live course programs, and even force-on-force training scenarios. Because it does not discharge any type of projectile and instead uses laser feedback, the SIRT Dry Fire Training Pistol can be used safely in nearly every environment and situation.
Here is a good introduction to the SIRT by Mike Hughes, founder of NLT and inventor of the SIRT.
