Thanks for the response. I just came back from the range. I go at least once a week, sometimes more. Each time, I practice something different. When I practice with my CCW pistol, I set the targets at between 20-30 feet. I believe that for self defense (No home defense); this is about the max distance you will need. If you are further than this, you should be running the other direction. Anyway; I regress.
Today, I practiced walking/moving, stop, pop 3 rounds, walk/move again, stop, pop 3 rounds, etc... And just for the hell of it, I did it today totally 1 handed. At 20-30 feet, 1 handed, all 12 rounds of the magazine were on target. Doing the same thing with my opposite hand; (You never know when you might not be able to shoot with your normal hand); I hit 10 of 12 one handed. (I need some more practice on that). Anyway; the recoil shooting from 1 handed; either hand; didn't bother me in the least. And, because there doesn't seem to be any "HOT" ammo out there, I will probably just stay with the existing recoil spring. I was just thinking if BuffaloBore, Double-Tap, etc... were to come out with a 1200 fps / 300+ ft/lb self defense ammo, if the 18# spring would be a better choice. "MORE IMPORTANTLY"; if I chose the 18# recoil spring, would it be "TOO MUCH" for common everyday ammo? In other words; would the slide not have enough distance retracting, because the spring is too stiff and the ammo too weak, and I risk the chance of stove pipes, mis-feeds, etc....? Thx....
