If you're not too invested in "pocket" use - - -
- - The three-inch 13 is an excellent piece. Enough weight to handle magnums without discomfort, enough barrel to reap some advantage from mag loads, and a full-length ejector stroke. Also, with a proper holster-belt system, the three-inch barrel is long enough to press against the hip and keep the butt up against your body, and so it CAN actually conceal BETTER than a small-frame two-inch, if you use an outside-waistband rig.
I personally prefer the round butt three-inch, but would feel extremely well armed with the revolver you describe.
I'm normally not enthusiastic about "pattern loading," but one school of thought is --- two rounds of 158 gr LSWCHP +P up first, for very controllable, highly accurate placement, and the rest with the mags of your preference.
Best,
