I test out the Underwood Ammo 155gr Gold Dot 10mm load in the Clear Ballistics FBI gel block (calibrated to mfg specs) with 4 layers of denim with the Gen4 Glock 20 (factory spring).

Chrono Data (average):

1443 fps, 716 ft/lbs energy

155gr retained weight

.812 average expansion

13.5'' penetration

As you'll see in the video, the bullet holds up pretty well with only minor deformation.
