Editing FB Vis (section)

===Military use===
Mass production started in the state armoury Fabryka Broni in [[Radom]] in late 1935, and the following year it was introduced as the standard firearm of Polish infantry and cavalry officers. Successively, other units were to be equipped, and by 1942 all other handguns were scheduled to be withdrawn from service. By mid-1938, it was introduced to the armoured and air forces. Before the [[invasion of Poland]], approximately 49,400 (out of 90,000 ordered) were delivered to the army.<ref name=ars/>

In addition to the 9mm, there was also a small information series of [[.45 ACP]] version, with 7-round magazine, but they were not produced in greater series.<ref name=ars/> Most probably only for the Argentinian competition the wooden stock-shoulder was issued but it has not survived.<ref name="York"/> A [[.22 LR]] variant also existed, but no details are known, and its series was not produced in great numbers.<ref name=ars/>

After the Polish defeat in 1939, the [[Germany|Germans]] took over the Radom Armoury and continued production of the Vis under the new name of '''Pistole P 35(p)''',{{sfn|Bishop|2014|page=248}} after its first year of manufacture while the suffix 'p' is for "Polnisch" (Polish).{{sfn|Bull|2021|page=136}} The German pistols of the first series had inscriptions VIS Mod.35 and P.35(p) on the left side.<ref name=ars>{{cite magazine |title=VIS |first=Wojciech |last=Weiler |date=2004 |magazine=Przegląd Strzelecki Arsenał |language=pl |volume=4 |number=2 |pages=51–60 |issn=1731-190X}}</ref> According to Hogg, about 375,000 pistols were produced for the [[German Army (1935–1945)|Heer]].{{sfn|Hogg|1987|page=95}}

Polish technicians working in the armoury stole many handgun parts to be assembled clandestinely and supplied for use by the [[Home Army]] in their [[Polish resistance movement in World War II|fight against]] the German occupation; when the Nazis discovered this, some of the Polish workers were hanged publicly in front of the factory while others were sent to [[Nazi concentration camps|concentration camps]].<ref name="wptech" /> The Germans moved production of barrels and final assembly to [[Steyr-Daimler-Puch]] in the "[[Ostmark (Austria)|Ostmark]]" (Austria). However, underground production of Vis barrels was started in Warsaw and Kielce-based [[Huta Ludwików]], and several hundred Vis pistols were assembled using parts smuggled from the factory, delivered to the Home Army, and used extensively during the [[Warsaw Uprising]], among other battles.

Vis pistols made by the Germans after 1939 were issued in four different series, each with small modifications to simplify production. In late 1944, all production was moved to the Steyr works in Austria, where the last simplified model of the fourth series was produced (with no inscriptions at all, apart from ''bnz'' signature). The Vis remained in production until April 1945. Generally, the wartime Vis were of much lower quality than the original Polish versions, and further declined towards the end of the war.<ref name="wptech" />
