I’ll keep my lanyard ring. Add a piece of shock cord and a stopper to the end of it and you have a easy on and off. Plus it stay on your hand when you are carrying other things like grocery/bags from the store or your keys while keeping the other hand free for your sidearm. I’m not saying it’s for everyone but every person who has tried my light out has switched to having a shock cord on their lanyard ring.You don't really need a lanyard ring to have a good lanyard on your light. I don't use the rings on any of my lights, in fact. I tie a "rhino loop" around the body of the light. It works best in one of the indented rings around most lights. We learned last week that if you remove the plastic lanyard ring that comes on some of the SureFire lights, it makes an ideal place to anchor a rhino loop.
Also it allows you to get a two handed grip on your side arm.
