Píšťala (the 2 on the top) was short. Hákovnice was quite long, with barrel at length of about a 100cms, see the pic. And in the Czech language, these were distinguished as different guns by 1403.
As regards the accuracy - I don’t think that these were any less accurate then a bow. And then again, pistols are also quite inaccurate on larger distances, yet the Czechs today have many times more pistols than long rifles or shotguns. It depends on the job it is supposed to do. If it is taking a heavy cavalry apart from short to medium distance (the major use in Hussite warfare), then they were very, very good. If it is taking down a heavily armored foot knight, then again, very, very good. Of course, use against fast moving light cavalry or infantry in open field was limited.
And nobody is arguing that it should be a primary firearm to go after the bandits. But as in-effective as it would be in such a scenario, they were period firearms and the player should have the chance to try. Go, maybe take down one, try to wield it as a club, and die - surely. In other scenarios, such as defending a house, a bridge or castle entrance against heavy cavalry/infantry, with one or two soldiers behind you loading them and two soldiers in front of you keeping enemy at distance - why the hell not?
And which other game should have period firearms if not the one that takes place where the PISTOL got its name?
