Federal Syntech Defense .40 S&W 175-grain Segmented Jacketed Hollow Point ammunition (part no. S40SJT2) is a purpose-built defensive load from Federal engineered for top-tier terminal performance in its class. On impact, the hollow-point bullet separates into three individual segments plus a deep-penetrating core, creating three secondary wound channels more than 6 inches deep in addition to the primary channel. The core alone achieves 12 to 18 inches of penetration in both bare ballistic gel and through heavy clothing, meeting the standard defensive shooters look for. A blue polymer jacket reduces barrel heat and friction while eliminating metal fouling, and Federal’s Catalyst lead-free primer adds another layer of reliability to every round.
