This Sig Factory Magazine fits Sig Sauer P290 pistols chambered in 9mm Luger. It comes equipped with an extended base pad that not only adds extra length to the tiny gun's abbreviated frame for a better grip and enhanced recoil control, but also boosts the magazine's ammunition capacity by 33 percent to a total of 8-rounds. While not as concealable as the standard 6-round, flush-fitting P290 magazine, this enlarged version remains unobtrusive and is small enough to be a good choice for carry in the pocket as a backup to the primary magazine inside the gun.
