IIRC, the Roth-Steyr and Roth-Sauer both came after the FN-Browning Model 1900, and certainly after the Borchardt of 1893. There were early manually operated pistols with strikers (Passler-Seidl, 1887), and by 1900 there were several auto pistols including the successful Borchardt and Luger as well as the Browning.
Also, IIRC, Glock claimed to have studied the Roth-Steyr in designing his firing mechanism, which operates on the same general principle of a partially cocked firing pin.

So the external hammer-fired semiauto pistol is a more recent, more highly evolved design?
