I keep my M&P pro 9mm with a weapons mounted light and my Kahr 9mm in a bedside safe. It is a little tight in the safe for both but not to the point of hindering their safe and quick removal. I got my M&P out to compare the TLR-1s light on it with a new flash light I recently purchased and apparently the pistol mounted light was resting on something that caused it to turn on at some point. Glad I found this out this way rather than when I try to look into a bump in the night situation. I'm now changing the battery and then I'll go make sure it sits in a way that doesn't allow it to push on the rocker switch. It will be kind of like making sure the light doesn't stay on in the refrigerator when you shut the door but I'm sure I'll figure something out.
