I'm glad to say that this article appears to be an outlier of stupidity, after reading a few more reports on this changeover, it does seem that the Army have actually thought about the decision and it's just this particular article that is daft.
The British Army website makes no mention of the 4 seconds to fire, instead saying that it was becoming difficult to maintain the pistol (not sure I entirely believe that either, but makes a bit more sense).
http://www.army.mod.uk/news/24697.aspxI did read elsewhere that 'Browning' was not in the running for the tender which makes me wonder what 'Browning'/FN Herstal are up to on tenders. I heard on the radio that when the new Belgian police tender came up, FN offered the HP. When the tender was finally won by S&W for the M&P FN appealed to the government and the last time I heard the tender was still wrapped up in paperwork. Anecdotally it would appear that FN still think that the HP is a viable modern firearm, even when they have polymer pistols in their own catalogue (that said I've shot an FNS style polymer pistol and hated the trigger... I must have something against FN pistol designs)
