A police operation targeting domestic violence that led to the arrests of almost 1000 people and the seizure of about 100 firearms has been blasted as a "political gimmick" by an expert.

NSW Police arrested 993 people and laid 2063 charges between Wednesday and Sunday, with 299 arrest warrants executed during the statewide blitz.
