For me, my uncle, cousins & neighbor, it wasn't fear of a double charge.What’s wrong with the .40’s?
Not much of a pistol person anyway but I do have 2 or 3
It was the high pressure to begin with.
All of us had different pistols from different manufacturers. First shots were spot on. Same follow up with slow fire.
Rapid fire 2-3 shots not so accurate.
The high pressure gives a heavy, sharp recoil impulse.
