My only experience with cold affecting function was with a Remington Viper semi-auto .22 rifle during Minnesota winters. It functioned fine in warm and cool whether, but in freezing temps, it would not cycle properly and was basically reduced to a single shot. However, I believe that was more of a magazine issue than a gun issue. whatever the cause, that may be part of the reason, the gun was only in production 5 or 6 years.
