Paul and Wilhelm had separated due to differences during this time. Following the success of the Dreyse needle gun ( Zündnadelgewehr) Paul turned his energies to improving on that design and producing a new one. During his entire career he had a unique ability to produce both the gun and the ammunition for it. Paul's first invention was a cannon and its ammunition. Paul was the engineer and designer but Wilhelm took on the task of manager for their interests with the Oberndorf factory. Paul engaged his older brother Wilhelm in working on a new gun system in their spare time after work. By December 1859 he had so impressed his superiors that he was placed on inactive military service and assigned to the royal factory at Oberndorf. Peter Paul was conscripted in 1859 as an artilleryman at the Ludwigsburg arsenal, where he worked as a gunsmith. Another brother, Franz Mauser, went to America in 1853 with his sister and worked at E. His brother Wilhelm was four years older. Peter Paul Mauser, often referred to as Paul Mauser, was born on 27 June 1838, in Oberndorf am Neckar, Württemberg. His older brother Wilhelm assumed many of his father's duties as he became ill. Of his seven sons who worked with him there, Peter Paul Mauser showed an outstanding ability to develop methods of operation that were faster and more efficient.

Originally located partly at Ludwigsburg and partly in Christophsthal, the factory transferred to the former Augustine Cloister in Oberndorf am Neckar, where Andreas Mauser worked as the master gunsmith.

King Frederick I founded the enterprise as Königliche Waffen Schmieden (literally: Royal Weapons Forges) on 31 July 1811.
