Can't go wrong with a Glock in 9mm. Though I wish they'd have gone for a metal-framed pistol instead of a polymer one.
I would be very interested to know what other weapons they put through trials, the BBC says they considered 7 other handguns. I'm assuming the HK USP and Sig P226 were in the mix, which leaves 4 other mystery weapons. I'm definitely not surprised they went with a polymer-framed pistol, they've proven themselves every bit as reliable over the last 25 years; add in the lower cost and its a no-brainer. In fact I wouldn't be surprised if the P226 was the only metal-framed gun they considered, and on average it's a good 250-300 dollars more per pistol than a Glock. The USP is polymer and around the same price as the Sig; I have no idea why agencies and militaries are still using that over-priced thing...
