Large Pistol (LP) Primers

Large pistol primers are essential components used in larger handgun cartridges, such as .45 ACP, .44 Magnum, and .40 S&W. These primers are designed to reliably ignite the gunpowder in the cartridge when struck by the firing pin, generating the necessary pressure to propel the bullet down the barrel. Larger in size compared to small pistol primers, they contain more primer mix, which is crucial for igniting the larger powder charges found in these calibers.
