I'm guessing that whatever the issue was, that it may have cured itself when you were fighting with it, trying to unjam the trigger. Since you had a failure to function, you'll want to run it past a minimum 250 trouble free rounds before considering trusting it for carry.
If I'm guessing wrong and it still binds, then try replacing the factory parts in the action and retest as above. If the problem still persists, send it back to Smiff again.
