Highest-capacity 9mm handguns, by standard magazine

Ranked on the standard magazine capacity each manufacturer lists for the base model. Where a maker also publishes optional capacities, they are shown beside the standard figure rather than used for the ranking — an extended magazine sold alongside a pistol is not the capacity the pistol is listed at.

How this ranking is built: Capacity is one of the few fields that ranks cleanly: it is a published integer, not a measurement with a basis. The caveat is scope rather than method — these are base-model records, and a variant with a different magazine is a separate record. Only source-verified records appear, every figure is the manufacturer's published one shown in both unit systems, and values marked ≈ were converted by this directory from the system the source published.

Reference information only. Not legal, purchasing, training, carry, storage, or assembly advice. A ranking on one published field is not a judgement about fit, suitability, or quality. Manufacturer technical data are rounded and may change without notice.
