Disclaimer: I do not intend to advocate breaking the law. If stories, books or movies can depict evil winning, and video games letting the player play as the bad guy, and no legal action is taken against them, why take action against me for talking about weapon legality in other countries?
Bonus (info from https://en.wikipedia.org/wiki/Gun_legislation_in_Germany#Firearms_ownership_license and https://en.wikipedia.org/wiki/Overview_of_gun_laws_by_nation#Comparison); since Germany has "may issue" firearm permits, it would not be a good idea for members of my organization (if it exists in real life) to be required to have them to be in the organization (even if we are able to do things such as bribe firearms authorities to make them shall-issue for the law abiding) if we determine that it isn't de-facto shall issue or if the requirements aren't what foreighn units would call "Too strict" (since people who are convicted felons, have mental disorders or otherwise deemed "unrealiable", ie "people with drug or alcohol addiction histories and known violent or aggressive persons" are automatically barred from getting firearm permits. And interestingly enough, despite stricter laws, Germany has more guns per capita than some countries with less strict laws, such as New Zealand, the Czech republic, or Finland, and has only like 0.5 than Canada, which has mostly far less strict laws). Thus, we must make do with whatever else is legal.
In Germany, for instance, for no-permit-needed sidearms, we would issue gas pistols (the Walther PK380 in particular. Lookup "Walther PK380 gas pistol" yourself). For no-permit-needed long guns, we would issue flintlock rifles and shotguns. Specifically, for rifles, the Pedersoli 75 caliber flintlock (http://www.midwayusa.com/product/372382/pedersoli-brown-bess-flintlock-muzzleloading-rifle-75-caliber-4175-satin-barrel-walnut-stock) would probably be issued, mainly for its caliber. For shotguns, the Middlesex village trading's double barrel flintlock (http://www.middlesexvillagetrading.com/MDBF.shtml), though I would like to find a maufactuerer to make 10-gauge double-barrel instead of a 20-gauge. We would probably also have 75 caliber blunderbusses from various manufacturers (not sure what to settle on).
Pellet/bb rifles and pistols would be from various manufacturers.
I'm sure some people would say "Why not bribe the firearms authority people?", and good question. Well, it is risky becuase you also can easily get reported or otherwise caught. I probably wouldn't, becuase the organization that I would run are political and enemies to the Illuminati, international banks, mega corporations, etc, plus with the fact that we'll be dealing with real weapons, which both morally and legally carry heavy responsibilities, and in many countries, especially the latter. In short, smart people, it is up to your own discretion, depending on the situation with many variables. Not-so-smart people, refrain from doing it all together.
And I have made a separate article addressing this; https://saynotodemocide1.blogspot.com/2015/11/how-would-media-depict-us-as-gun-owners.html.
