Needed accessory for concealed carry - Crimson Trace Laser Sight for 1911 Pistols

I like the practicality of assisted aiming if I am in a situation where there is inadequate lighting or if I have to engage an immediate threat from an unorthodox position. I don't rely on the red dot as a reliable sight picture but only as a aid. I believe that the laser grip I got for my Officer's ACP is a needed accessory for anyone who carries (which is why I have it on multiple pistols).
