Congratulations on your new Sako. You have one of the finest and most accurate factory built rifles available. As for the single set trigger, not all Sako's have it. It is available as an option on most models. It's likely from what you describe that your rifle has the standard single stage trigger. It's not a feature generally desired on a hunting rifle but would be an advantage for target or bench rest shooting. gg.
