Wow, even he can't get it right.
IT IS A STG-44 PEOPLE!
The MP in MP-44 mean Maschinenpistole, which means machine pistol. As you can probably tell, the STG-44 is not a pistol. That was it's coverup name because Hitler thought an automatic rifle was a waste in ammunition. But when he was visiting the eastern front, he asked his generals what they needed to win. One of the generals said they needed more of these automatic rifles. Since Hitler had banned the production of these rifles, he was furious, until he test fired one and loved it. Then he named it the SturmGewehr 44 (STG-44), which means Storm Rifle in English.
So when you are talking about this weapon, please don't call it a MP-44, call it the STG-44.
