Works perfectly, no fiddling with switch necessary! - ArmaLaser Laser Sight for Bersa

The laser is actually touch-activated, not by having to look for and fiddle with a tiny switch. After properly gripping the firearm, the side of one's middle finger makes contact with two thin metal strips on the laser's very thin rail at the point where the trigger guard meets the pistol's grip. It is actually more natural and easier to use than reaching for an activation button at the front of the trigger guard as with some, and more comfortable than having a bump/button on the grip as with some others. Yes, this happens only after one has first turned on the laser, similar to other laser sights that have a main on-off switch. However, just as one shouldn't wait to load a firearm until the exact moment of a self defense situation because that should have been done ahead of time, similarly, one should't be looking for an on-off switch at a critical moment because it should ALSO have been turned on well ahead of time, as when preparing to carry the firearm. The laser beam then activates immediately upon drawing and aiming the firearm. The laser beam is on only for as long as the firearm is held with a proper shooting grip. Upon re-holstering, the laser beam is off until the next time the firearm is drawn. Then, when retiring the firearm, or for some iron sight only practice, you simply press the on-off switch to turn it off. Now what could be simpler? It fits and functions perfectly! Having used many different types of lasers, this is among the easiest to use.
