The Tikka T3 borrows heavily from the Sako TRG design (which Sako got when they bought Tikka). The closed action goes a long way towards keeping debris out, and making the action stiffer. The smooth bolt keeps debris out of the bolt lugs and the angled lugs do not pack snow/debris in easily.
The T3 trigger shares a lot of the TRG design. The TRG-S rifle is a single stage like the Tikka and you can see the internal diagram below. The two stage TRG trigger has many similar features and all work well in cold weather (Finland).
The only time I've heard people having trouble with Sako/Tikka triggers is when they went around and messed with them.
