I own laser Max and Ct laser sights, to me the CT is not as awkward for on/off as the laser max.
There are pros and cons for almost everything you can think of, laser sight being no exception, but in my opinion a laser sight is an excellent addition to any sidearm, I think it is important to get use to the orginal sights, and learn how to use them but during low light conditions when they are hard to find the laser sight is a plus.
Keep in mind, most situations that require the use of a firearm occur at night so the laser sight may be a life saver, $350. is cheap insurance in my opinion.
