Never used a flashlight on a gun, me personally, I just think it makes you a more of a target in low light on or no light situations, but that’s just meWhat am I doing? Trying to figure out how a flashlight on gun works. Seems to be enough under the "shot spot" that aiming would be confusing. How do you use the light? Has anyone seen or used the 221B light with pressure cord activation-also manual, also attaches to either of several gloves they carry, with a sleeve inside glove so you move your fingers or thumb to activate. Might be usable for more than on gun, I have seen folks use on glove to do house/car repair. Is a light helpful for EDC? and what lights are used. Thanks All. ( see at 221B but don't let Sherlock Homes know you are at his address.)
