Forget the big clunky unintuative lights and go with a Crimson Trace Lightguard, it's sleek, holsters easily available to accommodate it in case you decide to carry it and adds virtually no weight to the gun. No manipulating a light with your trigger finger (never understood how anyone would think that is acceptable).

Yes I have a strong opinion on the light and no I do not work for Crimson Trace. Lol
