I'm going to start reloading pretty soon for my 3AT and have been trying to save all my brass. I guess I want to slow down the slide enough so the empty brass will not be thrown into the next county. After searching I found very little on replacing the factory P3AT recoil spring with different a weight. I don't want to effect reliability but it would be nice to have the empty brass fall 3-4 feet away. If you have replaced your recoil spring with a Wolff recoil spring what weight did you have the best results?
