This one is the one I use for home defense. A green mountain barrel, polished and reduced trigger. The trigger is about 4 lbs and breaks clean. Set up with tritium irons, a dot scope, green laser and flashlight. The laser is good for about 100 yards in full sun. The light is engaged with the thumb. The laser with the knuckle. I have them mounted where a normal comfortable grip will put them in service with very little movement. Both items are rechargeable so not so bad on the wallet if you train a lot.
Post up what you use please.
