Interesting commentary going here. I'd like to throw an additional .02 into the fray. I primarily own and carry only .357 revolvers. I started it all out with a 6" Security Six which was (is) used as a sidearm when hunting. It sees a diet of .357 JHP 158 grain and .38 Special JHP +P 125 grain. I also own an SP101 DAO in .357 and an LCR .357 that have never seen anything stronger than .38 Special +P's. I don't ever intend on shooting a .357 round thru them...but like the fact that "I can" if I should so desire. The heavier frame, especially on the LCR, aids in absorbing recoil. I practice with Remington .38 Special +P JHP 125 grain and can shoot over 100+ rounds and my hand feels no worse for the wear.
All that being said....my primary reason for the .357 was to standardize. I also like the fact that a .357 is a little heavier and stouter in areas of the frame that will handle the higher pressures of that round.
My LCR .357 is my EDC. Because of its short 1-7/8" barrel I choose to carry ARX 77 grain round that delivers a mean velocity of 1050 FPS and provides penetration well within the FBI protocol while opening up a wound channel similar to the heavier lead hollow point ammo. Those numbers can be documented
HERE. This ammo was designed with the shorter barrel guns in mind. I like that I can shoot a lower recoil round thru this short barreled gun and get faster follow up shots on target.
