Not 1911 but a custom 9x19 G20 gun

I’m running a 11# spring, and it works! Wonders of wonders. Heavy old slide but when you get it moving inertia takes over. Lots less mechanics involved. No swinging link, no frame lug recesses. The old 1911 has a lot of stuff going on mechanically and the recoil spring also has to seat all those mechanical surfaces consistently. Too heavy and it hammers the slide stop notch, too light would batter frame, link etc. It’s a real machine.
