I have an older Onyx (not a White Onyx) that shoots right around 50/50 with both barrels. This doesn't mean that yours will be the same. Every gun is different and every person's mount and sight picture varies as well. Berettas have a reputation for shooting "flat", but that doesn't mean yours will do so. Patterning a gun gives you the confidence of knowing where your gun is shooting, not just guessing that it's okay. Good luck!
