Josh,
You pretty much described JMB's tilting barrel design which encompasses almost every locked breech pistol ever made - Modern plastic included.
What separates the 1911 from most designs is controlled feed.
The lack of a hammer and hammer spring is a big factor in modern striker fired locked breech actions too. That changes the mechanics of the dwell time, and our ability as consumers to tune it.
Hammer spring, striker spring - potAto, potato. Sure, designs differ in the degree the striker is cocked by the slide. Even in a 1911 the main spring is poor choice for tuning.
It's not potAto, potato, there is a very significant difference. You may not understand it, but it is there.
I also disagree with GunGeek's assertion that the hammer/mainspring does not significantly affect dwell time. Mechanically, the barrel link controls
where the slide unlocks in it's travel, sure, but a stiffer mainspring and FBFPS do affect
when the slide retracts to that point to unlock in the firing cycle. You can feel the difference when racking the slide, and can see the effect in the brass when comparing both ways with hot loads, like 10mm or 45 Super.
