Shooting a lightweight snubbie like the LCR or the SW lightweight snubbies...don't worry much about a gun being able to shoot .357 Magnum. Sure, it's an option but it's an option that hardly anybody ever practices.
I own magnums all the way up to .454 Casull and I have even shot the .460 Magnum. I'd rather shoot these crazy powerful mofos than shooting an LCR in .357 Magnum. Yes, I did shoot the LCR in .357 Magnum as a range rental.
Can you dig it?
