My Wicked Laser E2 worked poorly with the safety pin needing to be held and in just the right position to fire. Took the end cap apart and a copper bit that bridges two of the screws was broken. I tried a solder repair but no joy. Looking for any solutions from a new end cap to anything that'll do the job. This old E2 may not have much life left, but would be a shame to retire it for this.
