If it helps I used the .3mm springs from this pack on my Mito trigger. https://s.click.aliexpress.com/e/_EQTXOD6
You have to cut them slightly to size but just put the old with the new for sizing. Some people have used .4mm rather than .3mm but I’m happy with my trigger being so light I could fire it by looking at it.
If you change it when it is out of the grip but the side back on put a rubber mat down and bang it reasonably hard on the back to check it doesn’t fire when cocked.
