My new 870 has two "trigger group" screws on the right side of it's receiver (as I'm sure they all do) and I'm trying to determine if it would be beneficial to to remove them and the trigger group when I clean it. If it would, are there any springs, or other small parts, that would "jump out" when the group is dropped? Thanks in advance for your advice as it's MUCH appreciated! Guy Wanna kill these ads?
