It seems nearly every police officer deployed to the frontlines either has a riot gun or shotgun now. There appears to have been a new order of guns made after July, because after that the model with an orange pump and labeled Less Lethal on the stock was seen everywhere.
It fires 12 guage ammunition. As the longest barrel less-lethal gun HKPF uses, it’s used for more accurate shows at individuals. The accurate operating range of most ammunition is 100 meters.
