Yes, sir you are correct. Spring is the factory one that came in it. That's why I stopped at 8grs and because it grouped descent. I haven't shot it much since developing this load. Appreciate your information. Dan.Great looking pistol.
Don't know what pound recoil spring you have in it but heavy loads will beat up the frame and slide since too light a recoil spring will cause the slide to bottom out and slam the frame. Loads need to be tuned to the recoil spring to protect the gun and for function.
I shoot 4.3grs of WST with a 185gr JHP( Nosler competition, Zero and Hornady) (750fps) and also with Zero 185gr LSWCHP, 185gr-200gr cast lead SWCs in my custom match 1911s with a 12lb recoil spring. Your 8gr load of power pistol is probably right around 1050fps.
There is a reason why the old GI 1911 rattles when you shake it.
