That is AWESOME!!!!!
OK, in all seriousness -
I really liked the ending tip about lubrication. For me, it's not necessarily about keeping the gun clean, but rather having vetted your lubricant for the type of cold-weather conditions you are expecting.
For those who carry concealed, there is also a difference between carrying IWB versus OWB. A gun that will function IWB actually may not function - or function well - carried OWB, and this is often in no small part due to the lubrication chosen.
We always think about clothing and how that may affect our concealment draw and re-holster strokes, but just as important should be the gloves you may wear. Be sure that you take the time to vet your gloves: for everything from its ability to allow you to properly engage/disengage crucial control surfaces to simply whether if it'll let your trigger finger into the trigger guard (and whether its material will allow your trigger to return properly) - all the way to whether if the way the glove sits on your hands or its material may cause issues with certain manipulations.
Jack Leuba once posted on M4Carbine.net how he had to take a cadre of tip-of-the-spear types and re-teach them how to manipulate their sidearms because the gloves they wore would occasionally snag in their pistol's ejection port when they released the slide following an emergency reload via the "overhand powerstroke" method.
Be sure to take your time to properly vet your gun and gear for conditions.
And for those of you who like to go to training classes, as I wrote in another thread, this is worth taking the time to watch. Here's perhaps one of this industry's most recognizable personalities and an excellent trainer, Steve "The Yeti" Fisher, giving a cold-weather run-down for perspective students, as-interviewed by the good guys at
Practically Tactical after an unseasonably cold and wet class up here in NE-Ohio a few years ago, in which students were apparently underprepared for:
