In early thirties Schweizerishe Industrie-Gesellshaft (SIG) company in Neuhausen designed a family of submachine guns. A military version MKMO (Maschinen Karbiner Militärmodell Oben) was first introduced in 1933, followed by a short-barreled police version MKPO. In 1935 SIG created simplified versions MKMS (Maschinen Karabiner Militärmodell Seitlich) and MKPS respectively, that used simple blowback action with one-piece bolt (the first version had delayed blowback action). 1,228 submachine guns of all four versions were made in total, issued to Swiss police, Finnish military (282 MKMS, of those 242 in 9mm caliber and the rest in 7.65mm) and Vatican Swiss guards. Most SMGs were manufactured in 7.65x21 and 9x19 calibers.
Note 1: "Seitlich" and "Oben" mean "Side Ejection" and "Top Ejection".
Note 2: some sources claim that version with delayed blowback action was called MKMS/MKPS, and the version with simple blowback action - MKMO/MKPO, but academic books provided blueprints that prove incorrectness of such statement.
