Editing FB Vis (section)

===Design===
The pistol bears many internal and external similarities to the famous Colt [[M1911 pistol|M1911A1]], which was the main inspiration behind the project – to the point that some consider the Vis to be an iteration of the Colt M1911.<ref name="sdski">{{cite web|url=http://bron.siudalski.pl/vis.html|title=Porównanie VISa do Colta 1911 i Browninga HP czyli najlepsze trzy pistolety II WS|last=Siudalski|first=Stefabn Jerzy|website=bron.siudalski.pl|publisher=Broń żołnierza polskiego|access-date=2024-03-28}}</ref><ref name="wildmen">{{cite web|url=https://wildmen.pl/strzelectwo/kultowy-vis/|title=Kultowy Vis|last=Szalaty|first=Piotr|date=2021-12-10|website=wildmen.pl|publisher=WildMen|access-date=2024-03-28}}</ref><ref name="trybun">{{cite web|url=https://trybun.org.pl/2015/12/23/5284/|title=Porównanie rozwiązań konstrukcyjnych pistoletów Colt 1911 i Vis wz. 35.|last=Turczyn|first=Andrzej|date=2015-12-23|website=trybun.org.pl|publisher=Trybun|access-date=2024-03-28}}</ref> The Vis was designed by [[Piotr Wilniewczyc]], and {{ill|Jan Skrzypiński|pl}} in 1930 at the [[Łucznik Arms Factory|Fabryka Broni]] (Arms Factory) in [[Radom]] under Director Kazimierz Ołdakowski.

{{bq|It would not have been a wise thing, of course, to initiate a design without considering existing products. It was, rather, a matter of selecting the most successful and modern weapon model and, based on it, to try and create the perfect weapon. The most successful of those previously designed were... the [Colt Browning] Model 1911... created by John Browning, the most talented of builders in the world in the field of automatic weapons.|Piotr Wilniewczyc, Vis 35 designer}}

The pistol operates on the [[short-recoil]] principle, with the [[Barrel (firearms)|barrel]] being cammed down and away from the locking lugs in the slide. Unlike the M1911, the Vis was not cammed by a link, but by a ledge of sorts, which contacts a portion of the barrel and forces it down as it is moved rearward with the slide by the recoil force. It shares some similarities to the Spanish Ruby .45 ACP.<ref name="York">{{cite book |last=York |first=William J. |title=VIS Radom: A study and photographic album of Poland's finest pistol |location=Greensboro, NC |publisher=Wet Dog Publications |year=2011 |pages=22–24 |isbn=978-0-9707997-8-4}}</ref> A characteristic feature was a trapezoid grip shape, wider at the bottom, offering good ergonomics and firm grip.<ref name=tward/> On the right side grip cover, the Polish pistols had the letters "VIS" in a triangle, on the left side—FB (for ''Fabryka Broni''—"Arms Factory").

The tests proved that the handgun was very accurate and stable (due to its size and mass, most stresses are absorbed and not passed on the shooter), while at the same time remaining reliable after firing more than 6,000 rounds.<ref name=tward/> The Vis was generally regarded as one of the best military pistols of that period.<ref name="wptech" /><ref name="trybun" /><ref name="wildmen" /><ref name="sdski" />
