In spite of the opinions above, the cause of the miss-alignment is the barrel lug. Bottom lugs are usually, on new 'gunsmith fit' barrels, oversized so the can be cut back to achieve that alignment at the rear face, and full lockup. This barrel would be considered "over fitted" for the frame. You could either start with a new barrel and fit it correctly or weld on the lugs then cut them back with a lug-cutter. Otherwise it would not likely affect functioning.
