I've been messing around with different riggers, springs and other bits to get better trigger quality but one of my guns has a disconnector spring that seems really tough.  I guess if I make it too light the hammer will follow the bolt home?

The disco spring should have no effect on trigger pull - though many have tried lighter hammer springs, or hammer springs intentionally installed backwards, to lighten the trigger pull.

FWIW, a reversed hammer spring DOES lighten trigger pull considerably, at the risk of not lighting off hard milsurp primers.

I would just get some JP reduced hammer/trigger springs, they usually come with a new disconnector spring also, but really the lighter hammer and trigger springs is what makes the difference. I wouldn't suggest installing the hammer spring backwards since it will allow the trigger pin to walk out while firing.

A light or malfunctioning disconnector spring could turn your semi into an unregistered machinegun.  The only time I've used a lighter disconnector spring is for my dedicated .22lr set up.  I love my J.P. Enterprises single stage trigger.

Sorry to be vague, I was referring to trigger quality on auto.  I have JP springs already and the semi-auto trigger is OK.  Obviously when the selector presses down the dosconnector tail it increases the trigger weight considerably; even more noticeable with the lighter trigger/hammer springs.  I was just wondering if anyone had clipped a coil or two of the disconnector spring to reduce the trigger weight in auto.

Yeah, in auto it'd add to the trigger pull.  disco springs are cheap - buy a couple and experiment.  Worst that'll happen is hammer follow, and that's what you keep some spares on hand for.
