Basically, the 357 full bore ammo problems were what lead to the L frame 'Smiths. Back in the day, police departments practiced with 38 Special and carried 357 ammo (usually 125 gr JHPs at 1500 fps). Once most departments started mandating magnum ammo for practice as well, problems started to arise. Heavier revolvers such as the Python, the 27, and the Ruger Security Six didn't have as many problems. S&W decided they needed to beef up their revolvers to take care of these issues, hence the 586/686. Of course, this was all just before North American PDs became enamoured of "crunchenticker DA huge mag semi's". Timing, as they say, is everything. - dan
