Does anyone have a source for lighter trigger springs? I know Shooting Sight makes a new hammer but that won't help with the pull weight. I've already polished and lubed my stock unit so the pull itself is smooth, maybe a little long. In reality the heavy weight of the trigger pull is the only thing keeping my SIG556 gun from being as accurate as my AR. If I don't concentrate hard enough I pull shots to the right because of it. I've tried searching online but have come up empty handed. I know there was a guy from Germany doing it years ago but that source seemed to have dried up. Any help would be apreciated!
