Small Pistol Magnum (SPM) Primers

Small pistol primers are a vital component in the ignition system of small-caliber handgun cartridges, designed specifically for use in calibers such as 9mm, .38 Special, and .380 ACP. These primers are smaller than their large pistol counterparts and are tailored to ignite the relatively smaller powder charges found in these cartridges. Composed of a brass primer cup, a sensitive primer mix, and an internal anvil, small pistol primers are engineered to ignite reliably when struck by the firing pin, ensuring consistent performance in a variety of shooting conditions.
