Winchester Defender .357 SIG 125gr Bonded JHP PDX1 – 20 Rounds

Winchester's PDX1 Defender line delivers bonded jacketed hollow point technology engineered for law enforcement and civilian self-defense. The 125-grain projectile features a bonded core that stays intact during penetration, promoting consistent expansion and weight retention even through heavy clothing and intermediate barriers. The notched jacket initiates reliable expansion at .357 SIG velocities while the bonded construction prevents core-jacket separation, ensuring deep, controlled wound channels.

Compatible with firearms chambered in .357 SIG, including popular duty pistols from SIG Sauer, Glock, and Springfield Armory. Loaded in reloadable nickel-plated brass cases with low-flash propellant for reduced muzzle signature in low-light encounters. Available in 20-round boxes or 200-round cases for training and serious stockpiling.
