I carried a L frame as a duty weapon for nearly 10 years, shot at least 2000 rounds per year, it felt good both double action & single. I had a model 19 & a model 15 combat masterpiece over the years & sold my 19 to buy a personal 586. Both 4 & 6 inch shot exceptionally, put Pachmyer grips on the company gun, kept mine almost original, just thinned them a bit. I'd vote 586 or 686, that under lug barrel & larger frame really seemed to help with double action control.
