    Help with Speer 9mm 124g +p. Info

    Is it bonded?
    Would like penetration/expansion info through various mediums.
    (especially auto glass and heavy clothing)

    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:
