This replacement magazine is a factory original from Ruger. Factory replacement parts are manufactured to the exact same specifications and tolerances and use the same manufacturing materials as the original parts which guarantees excellent fit and reliable operation.
Keeping a few extra factory magazines around is never a bad idea; extra magazines save loading time at the range and also serve as a backup for those days when you simply cannot remember where you put your primary magazine.
This mag makes it much easier to grip my LCP. Coupled with a Hogue grip almost makes it where the wife can manage it.
I love this extension and should have bought two. Adds an amazing grip to the tiny LCP and functions perfectly with everything from FMJ, hollow point and Ruger's new ARX ammo.
