I haven't shot the LCR357, mine's the .38 only model, but recoil was similar.
The factory grip does a very good job. I'd just shot 125 rounds of .45 in a IDPA match in freezing (literally) weather and running a box of .38s through mine..... yeah, you knew it went off, but it didn't bother me.
More recoil than a K-frame, but about the same as an Airweight J.
"And Shepherds we shall be. For thee, my Lord for thee. Power hath descended forth from thy hand, that our feet may swiftly carry out thy command. So we shall flow a river forth to thee and teeming with souls shall it ever be. In nomine Patris, et fili, et Spiritus Sancti. Amen."
