Mine came back today.
Before I sent it in, if I racked the slide without depressing the grip safety the trigger/striker/sear were not reset (if the gun had been dry fired). This made it possible to chamber a round without resetting the trigger, which would allow the striker to strike the primer.
Now, I can rack the slide without depressing the grip safety, but the trigger/striker/sear are reset, making it impossible to chamber a round without resetting the trigger.
Trigger is smooth, maybe a little heaverier, but won't know if it is actually different until I get to the range tomorrow (would go today except they are closed on Wednesday's).
