Why This Model

The real COP 357 was a last-ditch backup piece built for plainclothes cops and survival situations. Compact, brutal, and overbuilt for its size. This kit captures every bit of that energy. One sheet, every part punched out, trimmed, and fitted by hand. No allen keys. just patience and a sharp edge. The result is one of the most distinctive models in the ByteGuns lineup.
