This directory holds 6 verified records in the same class and chambering as the Glock G43X: 9x19mm Parabellum micro-compact pistols from 6 manufacturers. The nearest, the G43, sits 6 mm from the subject on published overall length; the furthest, 18 mm. They are ordered by that distance — a measured criterion, not a ranking. Nothing on this page is ranked or recommended.
The G43 is 6 mm / 0.24 in shorter overall, 1 mm / 0.04 in narrower, 0.5 mm less barrel, and 5 g / 0.17 oz lighter under matched conditions. It lists 4 rounds fewer of standard capacity. On barrel length, the published inch figures are identical, so this difference does not resolve in that unit.
The M&P 9 Shield Plus is 10 mm / 0.4 in shorter overall and 8 mm / 0.31 in less barrel. It lists 3 rounds more of standard capacity. 2 fields do not compare — overall height and weight — because the two sources publish them on different measurement bases.
The GX4 is ≈11.3 mm / ≈0.45 in shorter overall, ≈0.6 mm / ≈0.02 in narrower, and ≈9.3 mm / ≈0.35 in less barrel. It lists 1 round more of standard capacity. 2 fields do not compare — overall height and weight — because the two sources publish them on different measurement bases.
The CC9 is 12 mm / 0.47 in shorter overall, 3 mm / 0.11 in narrower, and 3 mm / 0.09 in less barrel. It lists 2 rounds more of standard capacity. 2 fields do not compare — overall height and weight — because the two sources publish them on different measurement bases.
The Hellcat 3" Micro-Compact is ≈12.6 mm / ≈0.5 in shorter overall and ≈10.8 mm / ≈0.41 in less barrel. It lists 1 round more of standard capacity. 2 fields do not compare — overall height and weight — because the two sources publish them on different measurement bases.
The P365 Nitron Micro-Compact is 18 mm / 0.7 in shorter overall, 1 mm / 0.04 in narrower, and 8.26 mm / 0.31 in less barrel. Both list 10-round standard magazines. 2 fields do not compare — overall height and weight — because the two sources publish them on different measurement bases.
These are related models, not substitutes: Glock publishes these records in the same Slimline line as the G43X. They are listed because a reader asking what else is like this pistol is often served by them, and kept separate because the maker's own line is a different relation from a competing model.
The G42 is chambered in .380 ACP rather than the G43X's 9x19mm Parabellum, so nothing below compares their cartridges. The G42 is 14 mm / 0.56 in shorter overall, 3 mm / 0.12 in narrower, 4.5 mm / 0.16 in less barrel, and 120 g / 4.23 oz lighter under matched conditions. It lists 4 rounds fewer of standard capacity.
The G48 is 20 mm / 0.78 in longer overall, the same width, 19 mm / 0.76 in more barrel, and 59 g / 2.08 oz heavier under matched conditions. Both list 10-round standard magazines.
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.
