Slow down.
Striker fired handguns have been around as long as there have been semi-automatic pistols.
Savage model 1907 made in 1913
View attachment 898903
The savage 1907 might be considered a striker-hammer hybrid sort firing system. Probably need to get a moving animated model from some one like C&Rsenal. In blue is indicated the striker that is linked to what looks like a hammer that functions more like a lever and the spring is around the striker-firing pin. The 1907 used a semi-double column magazine.
It also had a rotating barrel
""The curious premise of Mr. Ebert Searle's design is that the twist of the bullet moving down the bore was going to be enough of a time delay so the five degree rotation of the barrel in the opposite direction was going to be sufficient to allow this locking principle to reduce slide velocities and recoil.""
