Our take on the G-Sight 9mm Laser Training Cartridge

The G-Sight TBS2-9 is a battery-powered laser cartridge that drops into the chamber of a 9mm handgun so you can dry-fire at a target and see a red dot where the shot would land. It is a Class IIIa laser under 5 mW, so it is safe for indoor practice and works with laser training apps and targets that read the dot. It suits shooters who want cheap, quiet repetitions at home between range trips. Rivals such as the LaserLyte and Pink Rhino cartridges do the same job; the G-Sight is known for its app support and a dot that stays bright, though owners report the rubber O-rings and battery contacts wear over time.

Questions and answers

Does it fit any 9mm handgun?
It is sized for 9mm chambers and seats in the barrel like a snap cap. It is not made for other calibers.
Do I need an app to use it?
No. The laser fires whenever the firing pin strikes it, so you can aim at any wall or target. Apps add shot tracking and drills.
Is the laser safe for indoor use?
It is a Class IIIa laser under 5 mW. Avoid pointing it at eyes or looking into the beam, and use it as you would any laser sight.
How is it powered?
It runs on button-cell batteries inside the cartridge. Owners say the contacts can be finicky, so seat the batteries firmly.
How does it compare with a snap cap?
A snap cap only cushions the firing pin. This cartridge also shows a red dot where the shot would land, which is more useful for dry-fire training.
What is in the box?
The cartridge itself, with batteries installed. Extra O-rings are not included, and owners often buy spares.
Where is the G-Sight 9mm Laser Training Cartridge cheapest?
At Amazon, for $29.98, as of our latest check.
