I have a three .357 magnum revolvers and have owned a few others, which ended up sold or traded away due to various shortcomings.
My PC 686+ with 6" bbl is the most comfortable for firing magnum ammunition (duh). It's larger internal parts geometry and Wolff springs also give it the lightest & smoothest trigger pull(s). Besides the long barrel, it's 46oz loaded weight, make concealed carry out of the question. But, a finer woods gun would be hard to find! If it had a 3" bbl, like the OP's gun, I'd recommend he stop looking for a better .357 revolver! Buy lot's of ammo, a good holster, and enjoy his 686+.
But, something makes me "think" that the OP really wants a smaller-framed .357?
I also have a S&W 60-10 with 3" bbl. It is a welterweight powerhouse! With Hogue tamer grips, I can fire magnum ammo competently, but, not continuously & comfortably. That's OK, I practice a lot with .38's and fire enough .357's to stay familiar with recoil management. Wolff springs improved the trigger pull(s), but, it's not nearly as well as my 686+. At 27oz loaded and with it's fish-hook shaped hammer, I carry it concealed on a belt, not in a pocket.
I recently bought a Kimber K6s with 3" bbl and it will probably replace the model 60 very soon as my carry revolver. It's trigger is better and I haven't even replaced any springs, yet. It's DAO & de-horned all over, right outta the box, which allows me to shoot magnum ammo more comfortably and longer. It's 3oz heavier, but, holds 6 rounds instead of 5, so, I consider that a good trade-off. Those extra 3oz also help soak up about 10% of magnum recoil. That's not a huge difference, but noticeable. The sights on the K6s are more like those found on a duty automatic pistol: highly visible, snag-free, and rugged. They are drift adjustable for windage, or easily replaced for elevation. I haven't needed to do either; all of my shots have landed precisely behind the front sight dot, from point blank range to fifty feet. The only thing that I'm waiting for; is aftermarket grip makers to discover the K6s. The factory walnut grips are beautiful and of adequate size, but, they are a bit too smooth. The gun rotates in my hand during rapid fire and I'd like a few more options to test. Overall, the K6s is my new favorite .357 revolver. It's perfectly sized for concealed belt carry, and while a bit big/heavy for pant pockets, it's so sleek that it rides in a winter coat pocket very nicely.
