M3 trigger

I have had my M3 for about 3 weeks now and am learning my way around this thing when business allows some spare time.
Right now I am working on the trigger and I am not winning this battle. Not ready to toss in the towel but my frustration is growing.
I tuned the triggers on three Maverick and thus far the results are better than what I am getting out of the M3.
I watched Newman’s video on it and that helped but I cannot get the three stage mess cleared up. Get what you think is a good two stage set then go the bench and you notice that there is actually three stages with the second being a gritty creep just before it engages the sear.
Also cannot get the safety screw to move or the spring screw. Not too sure the spring screw even does anything besides retain the spring.
Does it help to take the trigger out and then polish things up a bit.
At this point I am starting to hope there is an aftermarket alternative.
Would think a gun of this price would have a much better trigger and that has me wondering if I am missing something.
Any helpful hints or advice would be appreciated very much.
