I bought one of those polymer holsters for my Surefire Z2 which I used to carry my light bezel up. Those metal prongs did scratch up my light pretty good. Naturally, it doesn't affect the light's performance, but after 2 weeks, one of the prongs broke (the one on the top) and the light would wobble in the holster. I wasn't happy considering I paid $20.00 for the thing so I threw it away. I could have sent it back to Surefire for a replacement, but the thing was cumbersome anyway.
