I was just in London. The adverage Scotland Yard Officer (the beat cop), at least the ones that have completed the required training, do carry now. They began training the officers accordingly due to the recent terrorist attacks and attempts. They're still a lot of 'Constibles' there that do not carry due to the required training, but as they complete it, they are issued Glocks and they are packing. They are even sporting BPV's now too.... At least from what I've seen.....
