The Swiss 7.5mm center-fire revolver cartridge was used only in the 1882 and 1882/1929 revolvers of the Swiss army. The case is of brass; the bullet is of jacketed hard lead alloy. Originally it was loaded with 0.7 grams (11 gr) of black powder.

It was popular with late 19th century European officers for its small size and light recoil and was adopted by the Belgian, Luxembourgish, Swedish, Norwegian, and Serbian militaries for their service revolvers.
