I have a Sig P220 with a Viridian C5L. I keep the C5L on the weapon when I'm at home and I tend to remove it for OC when I leave the house so i can fit the weapon in my OC holster. I do have a custom holster for the weapon with the laser mounted but I prefer not to OC with it since it has no real retention system. Now, the C5L mounts by the use of a threaded bar that must be screwed on or off with a screwdriver. I have done some searching and haven't come up with anything too useful but i was wondering if anyone knew of some type of universal QD adapter or maybe even a lever replacement for the screw so i can hopefully maintain my zero and quickly mount or remove my laser.
