When doing the trigger modification on the s400/s410 am I right in thinking that you put one crinkle washer on the trigger post and two crinkle washers on the other two posts (one top and bottom of the sears)the reason I ask is that I've just removed my trigger to add some crinkle washers and the trigger sear had one crinkle washer already fitted but the other two sears middle and top had a rubber o ring sat on top with a crinkle washer on top of those.found it a bit strange

All that you are achieving is to reduce side play. As long as it doesn't bind when replacing the side plate,it will be good to go
