An old (very old!) file of a Sci-Fi gun I designed after the model of the Steyr Pflager Katsumata Series D from Blade Runner 1984. 

This isn't a Steyr, it's a Tula Arsenal, in a nod to the Russian 'space gun', the Tula TP-82 drilling.

From the files it's a combination of Smith and Wesson K-frame, Schmidt-Rubin K31, HK MP5, and of course Mauser C96. 

I did the work in Photoshop but it's so old I don't even recall which version, maybe 5.0? I was going to clean it up but instead did the basic design then left it.
