Are holsters for the LCR in .38 special and .357 interchangeable?

I'm looking for a good kydex IWB holster for my LCR .357. I've noticed there's a lot more options for the .38 so I wondered if the cylinder is slightly longer on the .357 or if it'd fit in a holster for the .38. via /r/CCW https://ift.tt/3fiO6PM
