History

Adopted with the Reichsrevolver Modell 1879, Germany's first standard military metallic cartridge revolver. The single-action Reichsrevolver was considered stodgy by contemporaries (most nations had adopted double-action revolvers by 1883) but served reliably through WWI with second-line and officer personnel after the Luger became the primary service pistol. Reichsrevolvers are common German Empire antiques. Original ammunition is museum-quality.
