Yesterday I decided to change my Armalaser batteries. For some reason (perspiration?) on this occasion the screw for the bottom pin just below the trigger guard would not come loose. This resulted in the pin just turning in the Zytel housing. I considered filing a small screw slot on the head of the pin but it was too shallow to allow a deep enough slot. My other option was to grind the head of the screw off and order a new pin and screw from Armalaser. I did come up with another solution. I found a small washer with a hole slightly smaller than the head of the pin and an outside diameter that would extend past the outside of the Armalaser casing. After cleaning all surfaces with rubbing alcohol, I used a gel type (gap filling) superglue to glue the washer to the top of the pin and to the Armalaser housing. I let the glue set overnight and removed the screw the next morning. I took a pair of pliers and popped the washer off the housing and then cleaned the superglue off the housing with acetone. I think I will try a small amount of superglue on the body of the pin to prevent this in the future.
