A pal was issued a 686 when he 1st started working for DPS TX Troopers and he shot it out against 2 baddies one nite on a lonely TX highway. One was drt, the other was doa short while later. When asked very soon after the shooting as to how many rounds he fired, he said maybe a cylinder and a half... the investigator said no, your gun and speed loaders were all empty(24 shots). Leads me to once again trust the mighty 357 in tight situations but maybe reconsider in some situations- say if there had been a 3rd purp and my lone friend had the more recent 357 auto and 3 magazines he maybe could've laid down 3 by his self with the extra ammo he would've had on hand.... many things happen in a split few short moments... thank goodness he was able to go right to training and keep reloading against 2 jerks who were bent to kill him simultaneously during a tail light failure stop because they also had a trunk full of drugs and neither wanted to go back to prison.
