Good thread and good info, thanks all for sharing.
I have played around a bit with a 45 super light... I run a flat bottom firing pin stop, a 20 lb recoil spring with a poly buffer thingy on the guide rod.
My load is a Lee 255 cast from wheel weights , powder coated and enough Unique to yield 900 to 950 fps. I can keep my ejected brass within 12'
So far so good...
