Ever since I bought the Sig Lima365 Laser for my Sig P365, I have had a devil of a time getting it to activate with my normal grip. I was just about to give up on it and toss it, but I have come up with a simple solution that works. I had an old racing bicycle rubber inner tube laying around that I got from a bike shop for free. The markings on the inner tube are 20-622 (700 x 20C) so I assume that is the size. I cut off 1/2" of tube with scissors. I turned the piece inside out so the white powder was on the outside and wiped off the powder. I figured that the white powder, if left inside, might cause the rubber ring to slip. I took the Sig Lima365 Laser off my Sig P 365. I slipped the whole ring of inner tube over the switch and completely around the assembly and reinstalled it on my Sig P365. I've had it in place for a few weeks and carried it every day. The switch with the inner tube in place now allows me to activate the switch with my normal grip and grip pressure without thinking about it.
