I've been running into a problem with the switch placement on the M15, the existing guard stops short of protecting the switch from bumps especially when using a Slingshot where the hard surface of the vest can easily switch the rig off if you're not careful. My first solution was to tape a plastic bottle cap over the switch, but that was far from elegant. Here is the "Trigger Guard V1" (Made with a 3D printer) that attaches via existing holes on the roll motor housing. Has this happened to anyone else? If there's enough interest, I'd be happy to make a bunch more for people. -Chris
