Ruger announced that the LCP and LC9 pistols are now available from the factory with the new LaserMax CenterFire lasers. The CenterFire units use a red laser and mount to the front of the trigger guard.
The added bulk is very small and weigh only 0.5 ounces. The additional cost is between $70 and $82 depending on the model.
Both the LCP and LC9 are viable options as backup guns, and the added lasers may make them easier to shoot accurately under some circumstances. Smith & Wesson introduced the Bodyguard 380 with the integral laser, though LAPD requires the laser disabled if an officer plans to use the gun as a backup. I imagine they will forbid the carrying of the Ruger LCP with a laser as well.
