Usul,    The portland police glock problem was the ammo's fault. They were using a new .45 ammo that was made to higher pressures. Those pressures exceeded the capability of the glock. All glock pistols are rated for +P ammo so whatever they were using must have been hot. The .45 cartridge is already well known for it's power. There is no need to reinvent the round.    Glocks are awesome guns, period.
