PA sells them but it's a couple of months wait for them to get it. Go to your local Ace or True value and try and match up the spring to one they sell. It's something I need to do for my Sumatra as I want to try retuning it for a bell curve if posible.
The answer for the hammer spring is somewhere buried on this site. I remember the discussion and swapping out to a cut to length spring stock. The one in my parts drawer is 0.417" OD X 4.4" L w/ 0.056" wire. I am fairly certain it is the stock Sumatra spring.
Found a hammer spring & also replaced the cut valve spring. Slapped it together enough to throw a couple of 45gr slugs over the chrony. If you turn it all the way down to low power & come back around to low(hope that makes sense) I got 969.9fps for 94fpe at 200bar. It started raining when it stops I’m gonna try medium & high power to see what I get. Then I’ll try out my 55gr HP’s from Mr. HP.
