This is a factory extended 9mm 10-round magazine for Sig Sauer P239 pistols.
Sig Sauer P239 combines the rugged, combat-proven design of the P226 with a compact, single-stack package that’s optimized for concealability.
These factory extended magazines feature blued stainless steel construction, special witness holes for each round, and a grip-extending polymer baseplate. These magazines are ideal for home defense, trips to the range, or any other use where you can compromise the compact size for a few more rounds.
Remember to rotate your concealed carry magazines every 3-6 months in order to prevent unnecessary wear and tear.
