I'm with Rob on this one. Never have liked the idea of mounted lights just didn't have as many reasons as he has. I've had an intruder in the house. Came home at 2 am during the burglary. Had him trapped for two hours before I realized someone was there. I beat a strategic advance outside as he was between me and my firearms and I was between him and the doors. That was when I became "tactically" inclined. Letting a Rottweiler do the house clearing is more my style. If he bites it, I'll give him backup
I can stay in the dark until I hear him raising hell.
