Here’s a short video of me shooting my TNW Firearms M-31SA Suomi. This is a 9mm Parabellum semiautomatic carbine based on the Finnish KP/31 Suomi submachinegun. This TNW reproduction is an inexpensive way to experience a cool piece of history.
My TNW Suomi functions perfectly when using 36 round box magazines but my 72 drum needs some fitting. The ammunition used in this video was Russian-made Brown Bear 9mm 115 grain FMJ. I've also shot it with Federal 9mm 115 grain FMJ.
