I received the LG-449 for my new Ruger SR9C and easily attached it in a snap. The unit was very close to being on, but did need a small amount of adjusting. The next day I went out and played around firing my new toy and was impressed with the bright laser. A laser certainly shows how much you are moving around on the target! My shooting buddy was making fun of my small movements until I handed the gun to him! After shooting I walked in the house and notice the laser was not turning on now, it was completely dead. Now I am waiting to see how quickly I can get the Laserguard repaired/replaced. Certainly doesn't give one a warm and fuzzy feeling if these units just stop working for no reason. I will update this post when the problem is solved.
Pros: Easy install and to adjust. Bright laser
Cons: Died after first outing
