Do you have to change the slide plate when you change trigger connectors?
The Ghost Rocket kit comes with an armorers plate so that you can tune it.Are you talking about tuning a Ghost Rocket Connector? or just installing a "drop-in" connector. If your just installing a "drop-in" connector...no.
If your tuning a Ghost Rocket then you would use an Armorer's slide cover plate...once complete your original slide cover plate goes back on.
