I carried a Ruger SP101, ,357 mag for 8+ years in a Galco OSw, open top high-ride pancake holster. I have two, both with 2.25" brrls.
Last year when I wanted to buy a pocket revolver, I tried a couple S&W J-frames. And I tried the LCR, .38 special. The trigger is lots better on the LCR. So I bought it. Later, I decided I needed the LCR, .357 magnum. It's a few oz. heavier, 3.5, I think. So, I'd rather carry the lighter .38 LCR in my pocket.
But, the .357 LCR is a great little belt gun, in the same holster I carry my .357 magnum, SP101 in. I only carry .357 magnum rounds in my .357 magnum revolvers. I like the edge.
Ennh, I'm a Ruger fan. I guess I'll keep them all.
