I just find it hard to push/hold a button upward to trigger the light. It's hard to hold the button upward.

Great for training to improve grip, aim, and trigger pull. I use it the an app called laserhit and it works great.

To amazing customer service and product. About $10 more expensive than its competitors. A great supplement to weekly range work.

Laser fits snugly in all 9mm semi-autos. Works in browning hi-power, h&k p2000 and two glocks. I like the way they fit snugly. Works great in my sr-9c.

Laser trainer is easy to remove from the bore. Easy to slide into the barrel and gently push the trainer out. Only reason others have complained is that they rocked their slide too hard and it smashed the end of the trainer.

Good price for the quality of the laser bullet. Have been using this laser (the model with o-rings) in an average of 3 training sessions per week for over 3 months now. Planning to replace the cap after a while.

With each strike of the firing pin this laser's internal mechanism was being hammered/shifted deeper into the cartridge. Buyer beware.
