This directory holds 6 verified records in the same class and chambering as the Taurus GX4: 9x19mm Parabellum micro-compact pistols from 5 manufacturers. The nearest, the CC9, sits 1 mm from the subject on published overall length; the furthest, 11 mm. They are ordered by that distance — a measured criterion, not a ranking. Nothing on this page is ranked or recommended.
The CC9 is ≈0.7 mm / ≈0.02 in shorter overall, ≈2.4 mm / ≈0.09 in narrower, and ≈6.3 mm / ≈0.26 in more 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 Hellcat 3" Micro-Compact is ≈1.3 mm / ≈0.05 in shorter overall and ≈1.5 mm / ≈0.06 in less barrel. Both list 11-round standard magazines. 2 fields do not compare — overall height and weight — because the two sources publish them on different measurement bases.
The M&P 9 Shield Plus is ≈1.3 mm / ≈0.05 in longer overall and ≈1.3 mm / ≈0.04 in more 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 G43 is ≈5.3 mm / ≈0.21 in longer overall, ≈0.4 mm / ≈0.02 in narrower, and ≈8.8 mm / ≈0.35 in more barrel. It lists 5 rounds fewer 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 ≈6.7 mm / ≈0.25 in shorter overall, ≈0.4 mm / ≈0.02 in narrower, and ≈1.04 mm / ≈0.04 in more barrel. It lists 1 round fewer of standard capacity. 2 fields do not compare — overall height and weight — because the two sources publish them on different measurement bases.
The G43X is ≈11.3 mm / ≈0.45 in longer overall, ≈0.6 mm / ≈0.02 in wider, and ≈9.3 mm / ≈0.35 in more barrel. It lists 1 round fewer of standard capacity. 2 fields do not compare — overall height and weight — because the two sources publish them on different measurement bases.
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.
