The H&K-GIAT PDW (unofficial designation) was a concept personal defence weapon designed by Heckler & Koch.
Overview[]
The weapon was to be chambered for a 5.7×25mm caliber round developed by GIAT. It was designed in 1989 as an alternative to the caseless NBW. It seems that it was abandoned after GIAT became the parent company of Fabrique Nationale (FN Herstal). It is unlikely that this weapon was ever actually produced in any form.
