To add a little more about my "system", we have a series of 12 Passive Ifra-Red Sensors around the property that I can move around to focus on problem areas if need be.
When they go off, which they do every night (I'm up from 11 pm to 7-8 am) I usually grab my Merlin Fanny Pack with the .327, slip my Streamlight Stinger HP LED in the ring on the pack's belt, put on my Ghillie Coat and finish up by slinging my Night Vision (Yukon Ranger). When things get interesting I'll call my cell phone from the house phone, which gets left on the Sensor Receivers, and use my Blue Tooth. This way I can hang around outside and hear the Sensors as they trip then focus on those areas, as opposed to destroying my night vision by looking through my Night Vision Monocular more than necessary.
The good thing about having so many Sensors is that I can get a "direction of travel" based on the sequence in which they are tripped...........
If I'm having trouble with a savvy critter I'll also sling my 20 gauge, Remington 870 Tactical that has a Streamlight TLR2s, which gives me more range.
The key to my success with the Revolver is the Crimson Trace Grips / Sights. Early on I learned two things, one, the Taurus Judge (3" Magnum) was pretty much useless unless I was within 10', which is why I sold it, and that all of my night training with a Flashlight didn't help me much. I'm pretty good as long as my target is standing still but as soon as things get dynamic, all bets are off. The Crimson Trace changed all that.
Here's an image of one of our Sensors, which don't come "camo'ed", that's something I do.............
For those interested in more information on the Sensors, you can find it here.

P.S. The reason I went into so much specific detail is because of who, and what, the OP is and does (writer looking for details)...............
