Longer barrels

I didn't think of the barrel recoiling back would have a lot to do with the spring, but of course that makes sense.


So, the barrel (which I knew recoiled back) uses the cartridge power and the extra weight of the barrel (making more inertia to initially move the barrel) makes the cartridge appear not as powerful as it should be and the spring takes the actual recoil and the recoil of the barrel into account. Correct?


Since the spring is obviously important, there must be a fine line between a too weak of spring and one too strong.


Too weak of a spring results in excessive banging of the toggle and other parts, while too strong results in the weapon not wanting to operate correctly.


Amazing world we live in. How the heck did people like Borchardt / Luger or Browning come up with these ideas? I can picture many things, but I have trouble doing the opposite on a stupid 45 degree cut, such as in carpentry.


I appreciate the insight.
