This is a factory extended 14-round magazine for Sig P227 pistols.
Building off the proven design, experience and innovation of P220 series pistols, the P227 is Sig’s first combat-ready, double-stack .45 pistol.
These extended factory magazines feature the same durable stainless steel construction as their standard counterparts, along with an extended baseplate and enough capacity for 14 rounds of .45 ACP. Ideal for home defense, target practice, or other situations where capacity is crucial, these factory extended magazines will help you get the job done.
Don’t forget to rotate your loaded magazines (especially extended mags) every 3-6 months.
