Excerpt for T2C:
'Unlike rifle bullets, handgun bullets, regardless of whether they are fired from pistols or SMG’s, generally only disrupt tissue by the crush
mechanism. In addition, temporary cavitation from most handgun bullets does not reliably damage tissue and is not usually a significant mechanism of wounding.'
