I have been wondering about an aspect of pistol design lately: Why are almost all semiauto pistols made nowadays designed with a single surface barrel / slide lock? This surface would be the front of the ejection port on the slide, and the chunk of metal on the barrel around the chamber. The barrel essentially protrudes into the ejection port when the slide and chamber are locked up.
On older designs, like the 1911 and Hi-Power, there are a series of ridges on both the barrel and inside of the slide that lock up together. This design, although older, allows the barrel to unlock from the slide with less tilting since the locking area is distributed over several ridges. On a modern pistol, like a Glock, the barrel must tilt more in order to disengage its single locking surface.
Is there a hidden advantage to the more modern design? I'd think the older locking method would be inherently more accurate.
