I agree with Clemson
These guns are so light that you almost forget that they are there. I used to own a Ruger SP-101 .357Mag, 2 1/2" barrel 25oz. "it was a great gun", but try wearing an SP-101 on your ankle all day. It starts to hurt after only one hour and only gets worse as the time roles on. Now wear an ankle holster with a 12oz. S&W M-340PD in it, it's so light that you can wear it all day and with no pain.
What I would suggest anyone do, is buy the S&W,M-340 or M-340PD and start with .38spl so you can first start to get used to the Recoil and then slowly introduce .357Mag's. Eventualy you will get used to the recoil, "I did". I also suggest the .357Mag, 340 becouse you get both calibers in one gun and there is no difference in accuracy or velocity when shooting .38spl from either the S&W M-342 or M-340, and the M-337 or M-360.
