One of my first handguns I ever purchased was a Taurus 25 auto. It jammed alot and the bullet actually "tumbled in the air". Once while shooting cans i noticed that the entry point was oblong, almost like the bullet had actually started "rolling in the air".
Having owned a 25 auto ( sold it to a friend ), I can say that I wouldnt want it as my carry weapon. However, I wouldnt want to be shot with one either.
It all comes back to shot placement. I agree that someone on PCP might not immediatley notice that he had been shot several times in the chest with a 25. That being said, I would rather be shot in the leg with a .357 mag than shot in the face with a 25 auto.
