I've been a .357mag fan for around fifty years. I've owned a lot of different guns, including a model 19, model 27, and a model 28. I had Bill Davis build me two different custom guns in this caliber and both were "one holers". I also had/have three different L-frame .357mag revolvers. Two are 686's and I had a 586. All three of these guns shot at least 95% as accurate as both of the Bill Davis guns. The 586..on a good day...would shoot just over an inch for five shots at 50 yards with a select load. I consider these the most accurate revolvers SW ever made. The model 27 was no slouch, but the L-frames just feel better and shoot a bit better.
