I have a 686 Plus with 3" barrel. My son`s been trying for years to get me to part with it. lol.
I keep mine loaded with .38 +P "Short Barrel" Gold Dots for a home defense gun. It`s a dream to shoot with those loads.
However , as much as I like the gun , they`re just too heavy and bulky for concealed carry.
Get a K frame (6 shooter) with 23/4 to 4" barrel for that. Also , consider the Gold Dots I mentioned. They have way less muzzle flash & blast with short barreled guns.
