You can just fit the trigger too. $30 or so ans pretty easy.
I left my disco in because i swap between prod and std minor. The travel is really short with a .2mm disco and race hammer.
Removing the disco with the factory curved trigger sucks. The disco stops it travelling forward when the hammer is cocked. Without the disco the trigger can move all the way forward like in DA.
The SAO triggers have a second set screw so it can be adjusted to dial that movement out.
