there are 2 types of set triggers that look the same from the outside. One type allows the front trigger to both release the sear on the action and release the rear trigger if set to slap the sear. This type has a long blade on the front trigger when looked at from above when the triggers are out of the stock. The other type uses the front trigger to only release the set rear trigger. If your front trigger moves freely but you can't feel resistance at any point then it will be the second type. With this type of set trigger the rifle can only be fired by always setting the rear trigger first.
