I own a SW629 with a 4" bbl. Owned a Galco VHS shoulder holster for years to tote it, recently bought an El Paso Saddlery Tortilla (pancake) OWB holster and 2x speed loader carrier for it, so I can tote it more.
I keep it simple and carry some moderately warm factory loaded 240gr Hornady XTPs in my 29-3 3" as pretty much an all purpose round. OWB thumbstrap leather pancake. Speedloader in a snapped leather speedloader belt holster.
