There has been much debate over the last 20yrs, especially amongst Law Enforcement about whether or not lasers are an asset or a liability.   Just like the debates over using flashlights and how flashlights can and will become target indicators in low light,  lasers and flashlights have an on/off switch or an activate/de-active button.  Nobody with functional brain should expect to keep a flashlight on at all times or always have the laser activated.    Some think that putting a laser on a handgun means hitting your targets more accurately, but I’ve found that to not be true.  If you don’t have good trigger control you aren’t going to shoot better with a laser.   If you practice dry firing in a safe place in your home, you can practice seeing exactly how much movement your trigger finger is causing and then go back to the range and apply it.  After training with it, you’ll improve but not the other way around.

From what I have read, Crimson Trace Laser Grips come from the factory zeroed in at 50yds and if you are using one for CCW, you should probable make sure that it’s zeroed in to the top of your front sight picture before you carry it.    The statistics are that most robberies and attacks occur in low light and if your firearm is too small to have a light on it,  high definition night sights or something from Crimson Trace is an added bonus.   We see a considerable number of J-frame revolvers and Ruger LCP and LCR’s  with lasers on them due to the fact that the line of sight is so short that lasers can give confidence in a point and shoot situation, and remember not every time someone pulls a gun in self defense is it necessary to pull the trigger, as a matter of fact, most of the time they don’t have to, lasers can give a good guy a level of confidence in close ranges, at low light while a bad guy will clearly know what is glowing on his chest.
