"Colomba" means "dove" in Italian, the description of the weapons is a reference to the fact that the dove is a common symbol for peace in the Judeo-Christian religions. "Pasquale" is also Italian, the adjective form for "Easter" (the Christian holyday).
"Colomba Pasquale" is an Italian sweet bread that is traditionally baked during the Easter Season.
Needless to say the release of this weapon shortly before the Easter season 2021 has caused quite a bit of hilarity in the GBF italian community.
