In my opinion, there’s no point in carrying a .357 if you’re not going to take full advantage of the rounds capabilities. And for those who think there’s not much difference between .38+P and .357 out of a snubbie, then watch Paul Harrell’s video that proves there is a substantial difference in power levels. IIRC, he was seeing over 400fps difference between the two.
In the video he shoots 4" & ~2" bbl revolvers. With the 2" bbl's The 38+p gave an ave of 840 fps with 125 gr bullet, while the 357 gave an ave of 1250 with 125 gr bullet. Using those numbers- 38 = 195.8 ft/lbs while the 357 had 433.6 ft/lbs- More than Twice as much energy- So a 357 in a 357 has significantly more energy ( 2X ), than a 38, so there is a reason to carry a 357 loaded with 357's. So if I have the 638 it has Speer GDSB +p, while the 640 has Speer GDSB 357. If you have arthritis, hand injury, or other deficit, or do not like recoil go with the 38, If you want the most power that it can give, and you do not have the problems above ( YET ), than use the 357, twice the energy is significant at handgun levels. Be Safe,
