.45 ACP
A chambering recorded on 7 of this directory’s handgun records, published by 3 manufacturers.
Records sharing a chambering are separated here by the directory’s frame class, because those two fields together are what decides whether a side-by-side is worth publishing at all: a comparison is only built when both records share a chambering and a frame class. Capacity, barrel length, and weight are secondary readings within each group, and every figure below carries the dated source it came from on its own record.

By frame class
Frame class is this directory’s own normalization of the size class a manufacturer publishes, never a measurement it infers. Records whose maker states no size class are grouped last and stay unclassified, because there is nothing to normalize from — not because they are awaiting research.
