Germany did not use shotguns in WW2.
Yes, we know that.
But, In low BR, the shotgun is an attractive weapon for engineers.
It is mainly good for fighting very close enemies.
However, only the US has shotguns that can withstand military use.
Germany and the Soviet Union have only classic double-barreled ones.
Japan has no shotguns. Are you saying that a sword is enough…?
Give them more variety and options with their shotguns!
Here are a few candidates
Germans
Becker revolving shotgun
The Becker revolving shotgun is a German revolving shotgun, which utilizes an unusual blow-forward action that feeds ammo via a revolving cylinder. Although designed in 1899, the shotgun would not be produced until the 1920s by the firm Römerwerk. The shotgun operates via blow-forward action, in which the barrel “blows-forward” about an inch every time the weapon is fired, which automatically ejects the spent shell in the process.
The Becker is chambered in 16 gauge and is fitted with a six-shell cylinder, which only holds five shells, with the sixth chamber intentionally plugged up. Because the weapon forces gas back to eject the empty shells, having the cylinder loaded with six shells would cause a live shell to be ejected after the first shot. Because of this design, only the first four shells are automatically ejected and the last shell must be manually unloaded via an ejector rod.
Originally designed for hunting, it is believed that approximately 100 or even less Becker shotguns were manufactured.
Walther automatic shotgun
The Walther automatic shotgun is a rare toggle-action shotgun patented by the Walther brothers and manufactured by Deutsche-Werke in the interwar era.
Sjögren
The Sjögren Inertia is a semi-automatic shotgun invented by Carl Axel Theodor Sjögren in Sweden. Carl Sjögren had three patents for his design in 1900, 1903 and 1905. Shotgun was commercially introduced in 1907, and approximately 5000 were produced in Denmark until the end of production in 1909. It has been shipped commercially to several countries, including Germany, the United Kingdom and Russia. The Sjögren was a unique shotgun for its time, not only being a semi-automatic like the Browning Auto-5, but also because it utilized the inertia system used in many modern shotguns. An experimental rifle model chambered in 7.63mm was also presented, but did not receive any success on the market.
Soviet
Frolov Shotgun
These bolt-action shotguns, nicknamed “Frolovka” , are conversions of Mosin Nagant rifles into hunting shotguns, designed by engineer Pyotr Nikolaevich Frolov and manufactured in the 1920’s at TOZ. A surplus of Mosin Nagant rifles, most heavily battered during World War I and the Russian Civil War, were converted into 20 - 32 gauge shotguns. Such a measure allowed to quickly cover the lack of cheap hunting shotguns in Soviet Russia.
Winchester Model 1887
Another of John Browning’s famous designs, this shotgun was first developed in 1887 by demand of a repeating shotgun for lawmen and cowboys to use.
Since the Soviet Union already has lever-action rifles, this should also exist.
JAPAN
Type murata Shotgun
Some of the Type 13 and 18 Murata rifles used by the Japanese Imperial Army were converted to shotguns by having the bayonet and rifling in the barrel cut down to half the barrel length as part of the military’s profit-making project when they became obsolete, and were then sold to the private sector, where they served longer as hunting rifles than as military guns.
