I have a Terrus Maxus.
It came with a very large rapid style slip on silencer . I have since had the barrel screw cut .
They are pretty straightforward to work on , although care is needed when putting the trigger block back .
As with any thing they benefit from a light polish . Mine is also sleeved .
I have no issues with the trigger and find it as good as most other springers that I’ve had in that bracket.
