I just picked up a new springfield armory 1911a1 "loaded target model" and it has the skeletonized trigger and on the face of the trigger is a hole and behind the hole is a allen screw, Ive gone through the manual forwards and backwards and it dosent mention anything about this, but I think I read somewhere online about some haveing manually adjustable triggers and im curious as to if thats what I have here? its a small screw towards the bottom of the trigger. I took a couple pictures which arnt the greatest but maby it`ll help? Thanks for any info, Sean
