I own an LCR in .38 and a buddy owns the one in .357. The .357 version is 17oz. I've shot it with standard Remington FMJ, and it actually feels easier shooting .357 than my .38 model does shooting fairly hot (1050fps) .38 +P. My LCR has been co-opted by the wife, who wanted it for it ease of carry, and I put Federal Nyclad (not +P) for her as she's a bit arthritic. Shooting standard .38 spl (~800fps) it's easy and controllable, and I can shoot it all day.
