The "J" frame is one of the strongest frames out there! Bolt notches between the chambers, just like the 5 shot "X" frames, Freedom Arms and other firearms that handle the real tough stuff. The barrel shroud is almost nonexistent which means that a forcing cone split is next to impossible!

Now, alloy frames, different story but the M60? Stainless Steel through and through? The 357Mag in no way is going to test that frame, no way.

Triple charges of fast powder? Yep. Chasing stuck bullets with full power loads? Um, yep. A firearm "stress tested" by another owner and you pushing the envelope a bit? YES! But just because they are small doesn't mean that they are poorly designed! My, my!

I will take a 357Mag "J" frame LONG before I would take a "K" frame 357Mag, ANY DAY!

The "L" frame will take a standard 357Mag all day long, for longer than you live and not have one problem. Still, I would stake my life, and have, on a "J" frame in 357Mag.
