The best way to find out is to take some classes, or compete in some IDPA matches.
While you might be making 3-5" @ 7y (which is in the range of 'decent' I'd say) under 'range' conditions and slow fire, you might find your accuracy goes completely to pot under combat conditions or when trying to fire quickly or in low light.
Find a good trainer in your area, or make a road trip to So Cal and visit with CCWI. A trained shooter is a confident shooter!
