This is a red laser that fits on the trigger guard of the Ruger LCP II pistol. It emits a visible red laser that is easily seen at the distances you would be using a small caliber 380 defensive pistol. All visible lasers are limited to 5mW output by the US government for civilian usage.
Like every other red laser, you will be able to see the laser/dot on whatever you are aiming at, but you will not normally be able to see the actual beam of the laser unless there is particulate in the air (i.e. smoke or dust).
