Austro-Hungarian Roth Sauer Pistols |
Early Pistols are marked 'PATENT ROTH' on top of the frame, while Sauer's Savage-Hunter trademark appears in an oval on the grips. Later Pistols carry a
Gothic style 'Roth Steyr' name on the right side of the frame, with the Sauer logo on the grips.
Reported serials: A204
Georg Roth owned ammunition factories in Wien [Bécs - Vienna] and Pressburg [Pozsony - Bratislava]. He collaborated with Karel Krnka from 1898 on the
design of this pistol. It was patented by Roth and Krnka in 1900. The Roth factories were not sufficiently equipped for large scale pistol manufacture. The
pistol was manufactured by J.P. Sauer & Sohn in Suhl. The Patent was sold to Sauer in 1910. The pistol was named Roth-Sauer and sold under this name.
This, like so many of Krnka's designs, used an unnecessarily complicated long recoil action. The barrel and bolt recoiled together, locked by a lug on the
bolt engaging a recess in the breech. The bolt struck a cam at the end of the recoil stroke, rotating it through 20 degrees to unlock, and was then held
while the barrel ran forward alone. A spent case was extracted and ejected during this phase; the barrel tripped the bolt as it stopped, allowing the bolt
to come forward to chamber a fresh round. The bolt was rotated back to its locked position as it entered the breech, whereupon the entire locked assembly
ran forward to the firing position. The Roth-Sauer was fired by a partially self-cocking striker mechanism. As the bolt closed, the sear held the striker
with its spring under partial compression. Pulling the trigger completed compression of this spring and then released the striker. The mechanism was not
fully self-cocking, however once the striker had been released, it could only be re-cocked by manually re-cycling the bolt. All this complication seems
unnecessary in relation to the special 7.65mm cartridge designed by Roth for the Roth-Sauer, but somewhat weaker than the normal 7.65mm Auto round.
Additional features of interest include use of the cocking knob as a safety, locking the action when rotated, and an integral butt magazine which required
charger-loading through the open bolt-way.
