Up to you, but I know a lot of us would take the trigger assembly off and inspect it. Make sure everything fits normally and is not binding. Like Dave said check for burrs or anything that could cause it to hang up.

Other than maybe they put a dimple on the wrong sear and it’s really a standard one, or it has the wrong springs, not sure what else it can be.
Who knows. Maybe after taking it all apart, inspecting it, and putting it back together it will work normally…lol
