@Heym SR20 I can’t agree that there isn’t much paperwork caused by having mods ‘on ticket’. You’re correct that there isn’t in the first instance but what about if they require replacement? That requires you to dispose of the old and put in for a 1:1. That may be easy in some forces but where I am a 1:1 currently takes 6 months. That’s seriously impractical. Even if dealt with efficiently, it still takes up FLD time on something of no benefit to public safety.
I do though see why a ‘free for all’ might concern the police. However, requiring that an FAC be shown, with appropriate firearm, as a condition of purchase seems a reasonable compromise that would all but entirely eliminate the administrative burden of swapping a mod.
