Back from Europe. Guns I saw police using there:

Paris Gendarmes: Glock 17, HK UMP with T-2s, HK416 with ACOGs/Aimpoints, also featured neat red berets
Paris police: Sig Pro (pretty sweet imo, Bourne Identity vibes)
Brussels police: Glocks, M&Ps (!!!)
Amsterdam police: Walther PPQs
Copenhagen police: HK USPs

I thought it was just gonna be all Glocks like it was the last time I was in Jewrope, but I’m glad they’ve diversified (and I say this as a Glockfag).
