This is a game changer - Crimson Trace Laserguard Green Laser Sight for 1911 Kimber, S&W

I have nothing but good to say about this laser sight. It is a game changer. The fit is perfect on a Kimber Ultra CDP II. The green laser is very bright and indoors will even shed illumination into the room and onto the target. Use outdoors is limited, but it is useable in bright sunlight out to about 50 feet. On an overcast day, you can see the green dot at quite a distance. The workmanship is high quality. The on/off pressure switch works perfectly and is properly positioned. I am an older shooter whose eyes aren't quite what they used to me when I would pitch out golf balls and blast them with my .45. Now I should be able to do that again with this laser sight. No need to waste time with tritium night sights which are far slower that putting the green dot on the target. This laser definitely will improve speed and accuracy. This was the only option I could find to put a laser on my 3" barrel non-railed old school 1911 .45 pistol. It works perfectly, and as I said, it is a game changer.
