Open the side-by-side → How this set is derived: every record above is one the directory already publishes a side-by-side page for, so this page adds no comparability claim of its own. A record qualifies as a substitute where it is source-verified and shares both this record's chambering and its directory frame class; a frame class is assigned from the manufacturer's own published size label and never inferred from measurements, so a pistol whose maker publishes no size class appears in nobody's substitute list. Every figure behind the differences above is the manufacturer's published one, and a difference is stated only where both makers measured the field the same way.
What this page will not do: name a best choice, rank the records, or say which suits a person, a purpose, or a jurisdiction. Those depend on fit, training, lawful use and equipment this directory holds no verified data on. It lists what is comparable and what the sources publish, which is the part that can be checked.
