I had the opportunity to buy a real nice pre-lock 686 with 4" barrel and so I did. At the range, I shoot both .38 Special +P and .357. Then I started to think about home defense. I've read so much about the danger of hearing loss from shooting a .357 indoors, how it's too much cartridge to use at home, and how a better choice would be a .38 Special +P like the 158 gr. LSWCHP - the FBI load. I have a problem with this way of thinking. If I must use my gun against a BG in my home, I want to stop him as quickly as possible, preferably with one shot. Why would I deny myself the undeniable stopping power of the .357 in favor of the less potent .38 Special +P (especially if I have a chance to throw my ear muffs on first!)? I own a .45 semi-auto too, but I like the reliability of the revolver. What good is owning a .357 if you don't use it for its intended purpose? Burning up ammo at the range? Plinking? What do you think?
Sir, the .357 is an excellent choice for home defense. If ever you have to use it on an intruder:
(1) the report will explode his eardrums and void his bowels;
(2) the muzzle flash will set his clothing and hair on fire;
(3) the bullet itself will vaporize his entire torso, then pass intact through 17 walls and kill his accomplices waiting outside in the car.

Hope this helps, and Semper Fi.
