My current set-up for a night-stand gun is my Glock 34 with a Sure-fire weaponlight and new Glock 24-rd magazine. I like the long-slide/long-barrel to keep the muzzle away from the lense of the light (although, even with the 34 this is marginal). I like the extended mag so I don't have to reload. Night sights are important too.
You must have both a weapon-mounted light and a hand-held light. You shouldn't be pointing a loaded gun at an unknown target to flip on the WML to identify who it is. You also don't want to rely solely on a hand-held light, because they are not easy to shoot with, even with practice. Also, it may get dropped/knocked out of hand.
Always remember any use of lights makes your location immediately known, so using the lightswitch on the wall is often better.
