With SA revolver, one can fire two close shots with the first shot fired normally and the second, one's finger still holding the trigger back and cocking and slipping the thumb off the hammer spur to the firing grasp position, releasing the hammer.
I tried it a couple times with lesser powered loads and came to these conclusions for myself:
1. It is a close in, virtually contact distance tactic;
2. You need very credible control - there tends to be more roll as the gun is firing and recoiling as you are establishing full grip on the SA revolver;
3. More than contact distance away I was just as effective using it to cock it and pull the trigger quickly for both shots;
4. If I had real concerns about close in more than one shot required work to keep my butt intact, I'd carry a good DA revolver;
5. Very large bore magnums in SA revolvers have special considerations for me with high speed shooting. I'd opt for lesser powered, but not anemic, ammo for this use.
I am not very accomplished SA revolver shooter for high speed shooting. I am credible in that respect. I view them more as a sporting tool with which I am very proficient with them.
I personally don't care for SA revolvers for defensive situations. That's my experience. That's why I opt in favor of observation #4 if there are close in concerns.
