Yes, the Speer Gold Dot is a bonded bullet. I don't have specific data for the GD, but here is the Winchester Ranger Bonded which should be very similar to the 124gr+P:
9mm+P 124gr(1180fps)BONDED: (Penetration/Expansion)
Bare Gel: 12.6”/.68”
Through Denim: 18.7”/.54”
Through Heavy Cloth: 18.2”/.56”
Through Wallboard: 11.9”/.64”
Through Plywood: 15.8”/.57”
Through Steel: 22”/.42”
Through Auto Glass: 12.7”/.58”
Keep in mind, those are the maximum expansion points. The best way to measure expansion is to take the smallest diameter and the largest diameter into account:
