I found myself in a bad situation of needing a fire extinguisher to keep gas pumps from exploding from a car on fire. Since there was no breaker bar still attached to the chain, my Glock and Streamlight® TLR-1 HL® became a punch for Plexiglas so a fire extinguisher could be retrieved. There was damage to the lens cover but the light continues to shine on for another day! Very well built product.
