First you can protect yourself with a 38 just as well as most hand gun. Good ammo and a well placed shot will get the job done, but just to clarify knock down power is not something that goes eighth hand gun cartridges. If you sever a part of the nerve center with a well placed shot they should immediately stop presenting a danger to you. Everything else is up in the air.
There was a shooting involving a FED LEO where the suspect forced several agents to a wall. The suspect didn't know they were FED agents, just thought they were business men. When the suspect started to shove the last agent against the wall the LEO emptied his 38 that he had in a chest rig thru the back of his suit coat. The ammo was "FBI load" hp and all 5(chief's special) shots hit center mass. The suspect fled the store and died on the side walk. The suspect had a 12ga and if his response would have been to fight instead of flight he could of killed all three agents before passing.
I dont know if this has anything to do with the OP but just something to think about. If i had to pull my 642 (or most of my carry guns) out because of a threat 30 feet away it would be because there was no other way to avoid the confrontation.
OH and i still have some of the factory "FBI Loads" from the late 80's that were issued to federal agents and supposed to be close in power to the 357. I have never done any scientific testing but when shoot them out of my Model 19 a 357 load makes a bigger boom than the 38 FBI Load. Just shooting them the recoil about like a modern +p round.
