The Savage M.1907 (& similar m.1917s) was upscaled from .32acp to .45acp for the M.1911 trials. In fact it was the final remaining competitor to the Colt M.1911.
They utilize a camming/rotating barrel which is supposed to lock them up.
The (patented by the way) idea was that the bullet & rifling interacted to hold the barrel twisted in the "locked" position until pressure has dropped suffiently. This holds the slide closed through a lug on the top of the barrel which runs in a track machined in the slide.
I suspect that if the rifling turned the other way it might have worked better.
However, according to early hi-speed photography, they unlock FASTER than a baby browning .25 auto..... while not exactly apples to apples, an interesting comparison.
