The model 1898 Schwarzlose was a self loading pistol definitely ahead of its time. It was simple, powerful (for the period; it was chambered for 7.63mm Mauser), and remarkably ergonomic. It used a short recoil, rotating bolt mechanism to operate, and very cleverly had one single spring which did the duties of primary recoil spring, striker spring, trigger spring, and extractor spring. Why it failed to become a commercial success is a question I have not been able to definitively answer - I suspect it must have been due to cost. Edward Ezell theorizes that it was unable to compete with the Borchardt/Luger and Mauser pistols because those were able to be made with much more economy of scale. It is really a shame, because the Schwarzlose 1898 is the best of all the pre-1900 handguns I have encountered.
