Q: What firearms will the LT-PRO work with?

A: The LT-PRO works with firearms chambered in 9mm, 40S&W, 45 ACP, 38 special, .380 Auto, 357 Sig, 10 mm and 45 LC (.35 - .45 caliber) so long as you have at least 2” of actual barrel length.

Q: How do I install the LT-PRO?

A: The LT-PRO has a small plastic insulator located within the battery compartment. This needs to be removed before use. After removing insulator, insert the screw (included with the laser) into the adapter and thread the screw into the LT-PRO. This will expand the adapter so you will need to expand it only until it can be inserted snugly in your barrel. For .35 caliber firearms, the adapter will not need to be expanded very much. For higher calibers, the adapter will need to be expanded farther. Gently insert the LT-PRO into the muzzle of the pistol. The laser will activate when your weapon is dry fired.

Q: Will dry firing my weapon with the LT-PRO damage my firearm?

A: To help reduce strain on your firing pin, we do suggest using snap caps.

Q: How long does the LT-PRO activate?

A: When the hammer or striker is fired the laser activates for 100 milli-seconds to show where impact would have been if one was shooting with ammunition.

Q: The batteries die within a few days of installation. What’s going on?

A: The LT-PRO is a sound and vibration activated device. When connection is being made with the batteries, the laser is constantly searching for sound and vibration, therefore draining the battery power.

If your laser's battery cap has a rubber piece on the internal side, please be certain to twist the battery cap slightly to turn off.  Tap the laser gently to ensure it is off.

If your laser's battery cap has an exposed internal spring, please contact Customer Service via email at info@laserlyte.com and we’ll be happy to supply you with the updated version that does not require removal between uses.
