I was watching a programme the other day about a shooting in Luton.... the guy had bought several starter pistols, which were two tone in colour and bored out the barrels, then sprayed the slides black. Shot a guy in the chest and went on a rampage. I don’t think two toning a gun is the way forward. If he hadn’t of sprayed the slide he’d still have had a lethal barrelled weapon capable of discharging a round which was blue in colour 🤷🏻♂️
