Description
Grand Power’s extended 9mm magazine is built for shooters who run the K100 MK12, K100 X-Trim MK12, P1 MK12, or P11 MK12 and want to spend more time shooting and less time reloading. Grand Power designs these pistols around a rotating barrel system, and this magazine is engineered to feed reliably through that mechanism — a geometry that is more sensitive to follower design and feed-lip angle than a conventional tilting-barrel pistol, so using a purpose-built magazine rather than an adapted one matters here.
The 25-round capacity gives a meaningful extension over a standard-capacity Grand Power magazine, making this a practical choice for range sessions where topping off frequently breaks concentration, or for any discipline that benefits from a larger round count between reloads. The added length does extend below the grip, which is worth accounting for if you carry a spare — it will not drop cleanly into a single-stack pouch sized for flush-fit magazines.
Grand Power manufactures these magazines to fit their own pistol line, so the tolerances are matched to the original feed ramp and chamber dimensions rather than approximated for a generic platform. The finish is black. Fit and function should be drop-in for the listed compatible models without any fitting or modification required.
