i guess it could pass as an SMG though, with a longer magazine
It's a Mauser c96It's German.
The Mauser C96 (Construktion 96)[3] is a semi-automatic pistol that was originally produced by German arms manufacturer Mauser from 1896 to 1937[4] Unlicensed copies of the gun were also manufactured in Spain and China in the first half of the 20th century.[4][5]
Probably says Chinese becasue it is a picture of the one in Fallout 3, and in Fallout it is called the Chinese pistol.
Looks like a DL-44 blaster from Star Wars.
Stop picking ugly guns. Your models are fine, but the guns your modeling are ugly.
