Study of the persistence of gunshot residue (gsr) on gloves using colour test

During the discharge of a firearm, gunshot residues (GSR) escape from the openings in the firearm including barrel end, ejection ports, space between the barrel and cartridge holder in revolvers, and deposit on surfaces in the vicinity of discharging firearm. Detection and identification of these...

GSRs were more likely to be deposited on die surface of gloves when fired with revolver compared to the semi-auto pistol.
