A very quick presentation on the RedWings Blowback Pistols from Brazilian company, ROSSI by Gunfire... "Rossi RedWings pistols have a blow-back recoil system and all are equipped with such features as a RIS / Picatinny mounting rail, a skeleton hammer or an ambidextrous safety switch. An interesting addition in the box is a set of internal parts that allow you to adjust the gun to CO2 propulsion."
