The PPSH-41: How It REALLY Works
This video provides an in-depth look at the PPSH-41's direct blowback operating system, explaining its mechanical simplicity and high cyclic rate. Brandon Herrera details how Newton's Third Law applies to the bolt's inertia and recoil spring's function. The explanation covers the fixed firing pin, slam-fire mechanism, and the trigger's role in an open-bolt system, contrasting it with locked-breech designs for high-pressure cartridges.
