I got bit by the revolver bug, and am asking for some advice regarding my new toys. Try as I might, I am not as accurate with my 686 compared to my 325 (both 4" barrels). I think it is because the 325 has a smoother lighter trigger. Or, is the .45 an inherently more accurate caliber than the .357? Just wondering if practice and experience might dissolve this accuracy discrepancy---is it me or the guns?
