Speer Gold Dot Personal Protection 135-grain bullets are specifically engineered to solve the short barrel dilemmawhere standard defensive bullets often fail to expand at lower velocities. Utilizing Speers Uni-Cor technology, the copper jacket is electrochemically bonded to the lead core atom-by-atom, creating a projectile that is virtually indestructible. This specific 135-grain weight features a wider, deeper hollow point cavity designed to initiate aggressive expansion even when fired from snub-nose revolvers with 1.9-inch to 2-inch barrels. These projectiles allow handloaders to replicate the performance of the world-renowned Gold Dot Short Barrel factory load, ensuring consistent expansion and reliable penetration for self-defense applications.
