The Chropi GP10 was a submachine gun built by Chropi, Hropi (Greek, Modern (1453-);: ΧΡΩΠΕΙ) a Greek chemicals company, which used the "Chropi" spelling on its weapons. It was designed by a team under Sotiris Sofianopoulos (apparently an original Greek-Cypriot design) and was proposed to the Greek Army in 1975. Initial positive performance results during tests were followed by a final rejection with dire consequences for the company, which had improved its existing infrastructure in order to mass-produce the weapon. About 100 units had been produced, which were delivered to the Greek state and ended up in Greek Army storage facilities.
