Crimson Trace grips do not change the balance of a handgun in any way, shape, or form. I would also avoid internal lasers. They have been known to come apart and lock up a weapon from time to time. Stick with the external Crimson Trace.
One question you should ask yourself about the X200L - Are you going to carry the weapon with the light / laser mounted all of the time? I seriously doubt it, and if you don’t you just gave up your visible laser for concealed carry. Although the X200L would make for a nifty bed side home defense handgun / light / laser combo the Crimson Trace with X200 or hand held light makes a much more functional combination.
