PPS43c 9mm was an SBR but has since been taken out of the registry and is now a pistol. The stock was operational but is now welded closed, but if you want to SBR it, it will be easy to make an SBR again if you know what to do. Pioneer Arms converted it to SBR. It comes with 7 mags, all cut for 9mm: a Russian 3-cell mag pouch, a Thompson 5-cell mag pouch, a sling, and a parts kit.
