Small Pistol Primers

Most non-magnum handgun cartridges such as the 9mm Luger, .38 Special, .380 ACP, and .40 S&W use small pistol primers to ignite the powder charge. You'll see everything we have for sale in-stock below.

A small pistol primer measures .175" (4.45mm) and is not to be confused with the small rifle primer, which has the same diameter but not the same thickness. The two are not interchangeable.

Many companies produce SP primers, with Winchester and CCI being some of the top brands for reloaders.
