Highest-capacity .45 ACP handguns, by standard magazine
Ranked on the standard magazine capacity each manufacturer lists for the base model. Capacity spreads further in .45 ACP than in any other chambering this directory covers: the cartridge is large enough that frame size drives the figure hard, so the order here tracks the size ranking closely rather than cutting across it the way the 9 mm capacity list does.

How this ranking is built: Optional capacities are shown beside the standard figure, never used for the ranking — an extended magazine sold alongside a pistol is not the capacity the pistol is listed at. These are base-model records; a variant shipping 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.
