Here's a few more questions concerning the blowback action of handguns:
First off, is the pressure against the breech face from the case head of a detonating cartridge generally sufficient enough to cycle the slide? I am under the impression that it is, however I have also been told that it is typically the inertia of the accelerating bullet that initiates slide cycling.
Second, can a blowback pistol possess a heavier spring in lieu of a bulkier, heavier slide?
Also, what exactly makes the difference between straight blowback and a delayed blowback? If a delayed blowback functions exactly as it sound (a slight delay in slide operation), how is it that the cartridge case head would still possess enough rearward thrust to cycle the pistol? Is it necessary for these delayed blowback designs to have a massive slide such as the blowback, or can it have a svelter slide similar to a locked breech?
Finally, would it matter to you terribly if a potent-caliber handgun featured a delayed blowback instead having a locking breech?
For example, say there are two similar pistols of the same weight, accuracy and reliability... identical in every way except one has a locked breech and the other a delayed blowback. Which would you choose and why?
Thanks in advance!
