This probably has more to do with budget than quality. Not saying A Glock isn't reliable, just saying Glock gives their guns away to LE.
I would not concern myself with either malfunctioning because of the cold. I would be more concerned if I can get a gloved finger in the trigger guard or the operation of a safety with a gloved finger or numb digits.
As far as condensation goes, why would a Glock or Ruger be any different from a XD, Sig or HK? You still have to take care of the gun. They all have metal in them.
In short, you will probably be the cause of any issues with reliability due to the extreme cold and not the gun.
