I shot an IDPA-style night match last night and now know that buying CT laser grips was without a doubt a great move, as I intended them primarily for potential night encounters.

Three of four stages were shot without flashlights (using limited light as placed by stage creator). I am not nearly the best shooter in the group, but I waxed everyone else due to the laser. Very Glad to have them - though it is very different shooting the laser, versus shooting the sights.
