This new laser trainer fits all of the most popular pistol calibers, mounts inside the barrel and has the sound activated switch showing bullet impact with a laser dot. Every time your hammer or striker fires the small laser dot will flash for 100 milli-seconds simulating bullet impact. 

This is the next evolution to the LaserLyte line of laser trainers. This model installs from the muzzle of the barrel and fits tight with the use of LaserLyte's patented arbor and taper system. The system will fit the weapons chambered in 9mm, 40S&W, 45 ACP that have a minimum of a 2 inch barrel. The LT-Pro will also fit calibers 38 special, .380 Auto, 357 Sig, 10 mm and 45 LC. 

The training possibilities are expanded with this model because the trainer will not extend past your muzzle more than .25 inches. This nearly flush mounted laser trainer makes it easier to train from the holster, concealment or close quarters. The mounting system will retain the laser firmly in the barrel during any reloading drills. (LaserLyte strongly recommends the use of snap caps) 

This is simply the easiest way to train without ammo for any of your pistols with a 2-inch barrel or longer. The popular calibers listed above can be expensive and hard to find for regular practice. This is the most effective laser training system that will meet all your needs.
