I cannot seem to find the balance between free action of the blade and a solid no play lockup. Have tried everything I know so I need some expertise to help me get her where I want her to be

How new is the knife I learned with my paras that didn't drop free at the beginning to break them in first then I clean, oil and set pivot and zero play with free falling blades

I've carried it 5 out of 7 days of the week for about 6 months

If you can't find that happy medium just turn the pivot screw until there is no play then just let it break in . Remember when adjusting just do very small turns of the screw because sometime to hit that sweet spot you won't even see or feel the screw turn.

If the above doest work you might need to take it apart to clean and lube it .

Balanced tension between the pivot screws and stop pin screws is the secret!
 
My m4 when received the blade was favoring the clip side and wouldn't free fall so I just barely loosened the pivot screw and it's about centered and falls freely with no play . Every knifes a little different though. There was also a few loose scale screws so just tighten those up.

I have the same prob with mine. Saw a YouTube video of a guy addressing this who gently put some 1000+ grit sandpaper to the inside of the liner to make it completely flat. After he did that the blade was free swinging with no play.

Polish the washers. Polish the blade where the washers make contact and the same for the liners. Polishing can be done with very fine wet/dry sand paper. The washers can be polished on a ceramic sharpener. Then clean everything and apply an ultra thin layer of grease, i use red bearing grease. Super super thin layer. Like a dab applied with a q-tip.
 
I agree with the first answer. With spyderco and any knife really, it's important to break it in, this can be expedited by opening and closing it repeatedly and just playing with it. After a few days or a week, it will be buttery smooth. If not, wait another week. If it's still stiff (and it shouldn't be) then use a t8 torx driver to SLIGHTLY loosen the pivot. Just barely turn it. Slight changes make the biggest difference. If that doesn't help, then it's time to take it apart, clean it with warm water and soap, dry it COMPLETELY, then oil it with mineral oil or coconut/vegetable oil if you plan on using it for food prep and put it back together
 
a few flicks should be enough to break it in, it's really only about polishing and grinding away a bit of the bronze washers. You'll still have to accept at least a hair of play if you want it to free drop.
 
I leave all the screws backed out a bit and flick the knife open a few times before incrementally tightening each screw. Sometimes I loosen a few and push the blade side to side before tightening them again. Sometimes one of the pivot screw has to be very tight and the other not so tight.

I lube with Royal Purple synthetic gun oil. Super slick and doesn't dry up from what I can tell.
