Noooo! The tailcap boot on my L1 is starting to wear down, the nubs are almost gone. Is it possible to get a new boot for it? I hear Surefire is pretty stingy when it comes to that stuff.
You'll need a whole new Z62 TailCap. Normally SureFire does not replace worn out switch boots or tape switches. They are designed to be grippy and therefore like vehicle tyres will wear down in use and need to be replaced.
Still, I don't think theres any harm in calling SureFire to ask.
