Laserlyte Laser Trainer Cartridge Review
(Laser Bullet)

My friend recently received a LaserLyte Cartridge Laser Trainer for use in his 9mm Glock 17 and Glock 26 for Christmas. He brought it to the range to show me and let me try it out. Later I bought my own.

What Is A Laser Bullet?

A "laser bullet" is a shaped brass cartridge that contains a laser, 3 batteries and triggering device. It is used to safely practice dry firing your pistol at home and "shoots" a brief (100 milliseconds) burst of laser light at the target of your choice every time you pull the trigger. Each time you fire it, you have to rack the slide of the pistol. The "cartridge" is held inside the chamber of the pistol by two O-rings and is not ejected because it has no rim for the ejector to catch on. You shoot it as many times as you want by simply pulling the trigger then racking the slide. One set of 3 batteries contained inside lasts for about 3,000 firings.

How To Use It

  1. Lock back the slide of your pistol/firearm.

  2. Manually load the laser bullet into the chamber.

  3. Release the slide.

  4. Aim and fire at any suitable target.

  5. Rack the slide and fire again. Repeat as many times as you want to practice laser bullet dry firing.


Package & Instructions


Removing It From Your Pistol

  1. Lock back the slide of your pistol.

  2. Using a rod inserted into the muzzle of your pistol, gently push the laser bullet out of the chamber.

  3. Close the slide and secure your pistol.


Why Use A Laser Bullet?

  1. They are a great tool for training with your firearm when you are away from the range.

  2. You can practice dry firing your weapon and actually see what you would normally hit.

  3. It is safe and quiet.

  4. It's a cheap way to increase your skills with your firearm. After the initial cost (about $84) you can dry fire  as much as you want up to 3,000 firings without having to change the batteries (simply unscrews for battery replacement). Batteries cost about $5 for ten batteries. It contains 3 batteries.


What Is Bad About It?

Nothing really. They let you practice as much as you want for no cost. The only problem is that they don't simulate the real life recoil and loud bang of the gun.



I tested the laser trainer in the shooting range and shot at white paper plate targets at distances of 20 feet and 50 feet. The laser dot was clearly visible against each target. Each time I pulled the trigger, a "beam" shot out of the barrel of my Glock 19 and reflected (for 100 miliseconds) against the target. The "dot" was bright red and easily visible at both distances. The shooting range was well illuminated.

The cartridge was presented to 4 other individuals at the range as well as two range masters. All were impressed with the function and the price. One of the range masters who teaches a gun training course mentioned that she may have to look into them some more and possibly get some for her gun training course as a learning tool for the students.



GET ONE! They are a great training device. GET ONE. They are a great way to improve your shooting skills with none of the cost, noise or danger of firing live ammunition.

Note - My friend's son-in-law has a laser bullet and showed it to my friend who was so impressed he bought one for himself (his wife's Christmas gift). My friend showed it to me. Now I have to get one for my Glock 19 and Glock 26.

Laser Trainer


I finally ordered my own Laserlyte Laser Trainer Cartridge. I ordered it from Amazon.com on Friday and it arrived on the following Tuesday with no shipping charges (I'm an Amazon Prime Member). It comes with the batteries already installed in it. 3 spare batteries (it takes 3 to operate) are also provided in the package. All I had to do was install it into the chamber of my Glock 19 and pull the trigger.





I was advised that when I hand inserted it into the chamber, I should push it in all the way forward with my finger, then slowly move the slide forward. The O-rings on the bullet keep it aligned in the barrel and the friction keeps it in place in the chamber. The "bullet" has no rim on it so the ejector of the gun doesn't remove it. All you have to do is point the gun and pull the trigger. A laser beam shoots out of the gun as the firing pin (or in my case striker) contacts the rubber backing of the bullet. (Initially the backing was smooth with no marks on it. After shooting it a few times you will notice a firing pin impression on it.) Also, at least for Glock pistols you have to shoot it without the magazine in the gun. This will allow you to shoot and rack, shoot and rack, shoot and rack... without interruption. If the magazine were installed you would have to manually release the slide each time before you shoot.

The first several times that I shot it, I was surprised on how terrible I was. It looked like the laser wasn't shooting accurately on the target. After shooting it more I found out that it was me and not the gun. I also observed that when I shot the laser would make a little "Z" (like in Zorro) on the wall of my house. This it turns out was a result of my trigger pull technique. Practice made this go away.

After shooting it a while I found that my trigger pull did improve and I was hitting the target much more. It's of no consequence, but I did notice that when I racked the slide to reset my trigger, sometimes the laser will shine for a fraction of a second (during the racking process).

Removing it from the chamber of the gun is easy. Just shove a pencil (with an eraser) into the muzzle of the barrel and gently push it back. It will move out of the chamber, fall down the magazine well and out of the gun.




  2. Training with the Laserlyte laser trainer gets you to notice and improve your aiming and trigger pull. The nice thing about it is that you actually see the evidence of your mistakes and can practice can improve them.

  3. I think that the device itself may get better with use. I'm thinking that the O-rings that center it in the chamber of the gun will become lubricated and that any uneven-ness that they initially had may correct itself.

Message: I recently bought the laser bullet, 9mm. In my sig 229 it works great, a short pulse from the laser that is clearly visible. But in my wife's Ruger SR9, the firing pin does not pull back after striking the primer so the laser stays on until the slide is racked. This makes it very difficult to see where the shot would have been and confuses the laser target since it records multiple hits. I noticed in our article that the glock, a striker fire like the SR9, you saw only a light pulse, so I assume the glock does not leave the firing pin in contact with the primer after it is fired but uses the momentum of the striker to extend the firing pin to the primer and then pulling back like the Sig, and other hammer/firing pin style pistols. The rest position of the firing pin on a pistol/revolver with a hammer does not extend the firing pin past the slide so the gun can be safely carried with the hammer down and the firing pin not in contact the primer. The sr9 is our first striker fired pistol, so before I read your review with the glock, I assumed that the sr9 was representative of striker fire mechanisms and there is no need to use momentum to extend the firing pin since you would not have a live round in the chamber without the striker being in the partially cocked position. Is there something wrong with the SR9? Thanks. Pete
