Speer 3992 Gold Dot Personal Protection 9mm 90gr projectiles are the industry standard for defensive handloading, specifically where high velocity and rapid expansion are required. Using the Uni-Cor electrochemical process, the jacket is bonded to the lead core one atom at a time. This technology eliminates core-jacket separation, ensuring nearly 100% weight retention. The lightweight 90-grain design is frequently used for .380 Auto or high-velocity 9mm Luger loads, offering significant energy dump and reliable expansion. Defensive Application Engineered for duty performance, these bonded hollow points offer elite barrier-blind expansion. The 90-grain weight is ideal for sub-compact handguns where maximizing velocity is key to ensuring expansion.
