Same here. The mainspring was weak and the gun would not fire DA at all, and took several strikes SA. That could have been corrected, but its major defect could not.
That gun has no locked breech. It is of a class called gas-retarded blowback, in which gas from the firing is bled off and used, not to operate the slide, but to delay its opening enough that the case does not burst from high pressure. (In more conventional pistols, that delay is effected through a mechanical lock.)
At one time, there was a fad for such guns. I read that one of the German states had put out a spec for a new police pistol that required both 9x19 caliber and a fixed barrel. So Steyr, H&K, and Walther set out to try to get the contract. The Walther entry, the PP Super, didn't use 9x19, but was chambered for the 9x18 Ultra, a more powerful round than the 9mm Kurz (.380 ACP). H&K's entry used a reverse piston to delay the slide and Steyr's Model GB let the gas blow forward inside the slide to delay its movement. The Rogak was a licensed copy of the Steyr GB. But the Steyr depended in a tight enough frame-slide fit that gas would be contained; Rogak's workmanship was so poor that the gas escaped before it could take effect, and the slide came back too fast, resulting in the extractor tearing the heads off the cases.
Rogak's "solution" was to grind off the extractor! Of course, that meant that an unfired case could not be extracted to unload the gun, so Rogak's instruction manual says that to unload an unfired round, point the gun up and the round will fall out of the chamber. Might not go over too well on an indoor range, though.
IMHO, the Rogak is an interesting example of how not to design a gun (Steyr's design was not very good), how not to manufacture a gun, and how to get some gunzine writers to hype anything!
It has another interesting feature - it was made in Morton Grove, IL, which attained a certain notoriety as being the first town in the U.S. to totally outlaw handguns, a law that has since been repealed.
