Tuning FX Dreamline Hammer Spring Spacer

[slush]

I want to add a spacer to my FX Dreamline Dream pup Hammer spring adjuster. I found a metal washer at my local hardware store. The washer is 9.60 O.D. and 1mm thick.

Is there any issue using metal washers?

Also are there any problems, with stacking 3 washers to get 3mm thick spacer?

Did you try just a heavier spring? Then to find balance you're going to add reg pressure.
I was thinking adding delrin washers as a spacers. No new for lube.
