Available for .40/10mm caliber, 9mm Makarov, .50 Action Express, .357 Sig, .38 Special, and others, Speer TMJ Handgun Bullets are an affordable yet extremely powerful choice. These Total Metal Jacket (TMJ) bullets are manufactured with Uni-Cor technology. With this, molten lead is poured directly into the jacket, thereby encasing the lead core completely in a flawless jacket. Based on this innovative design, the base of the bullet will not experience deformation while under pressure. In addition, these bullets will not foul ported recoil compensators, and they are swaged twice for a uniform heel and absolute consistent diameter.
