Glock 43X vs. Shield Plus

Smaller and higher capacity, in the fields that compare.

These two land in the same directory class — micro-compact 9x19 mm — from different manufacturer wording: Glock calls the G43X a “Compact Slimline,” Smith & Wesson calls the Shield Plus a “Micro-Compact.” That shared class is why this pair also has a generated side-by-side page in the directory’s compare section, linked at the end of this article.

Where the sources compare cleanly, the Shield Plus is the smaller pistol: 6.1 in against 6.5 in overall, and a 3.1 in barrel against 3.41 in. It also carries the higher standard capacity, 13 rounds against 10, and ships a 10-round magazine alongside. Glock lists no optional capacities for the G43X at all. A shorter pistol holding three more rounds is the practical shape of this comparison.

Only two of the four dimensional rows survive that comparison, though, and the rest of this page is about why.

Both sheets say 1.1 in. They are not the same measurement.

This is the most likely thing to be got wrong about these two pistols, and it is got wrong because the numbers agree. Glock publishes an overall width of 1.10 in for the G43X. Smith & Wesson’s specification sheet publishes 1.1 in under the label Frame Width, with a sub-row immediately beneath reading “(Less Controls): .94 in.”

A frame width and an overall width are different measurements: one describes the frame, the other describes the widest point of the pistol including whatever stands proud of it. The sub-row is what gives the game away — a figure that has a separate “less controls” variant is a figure that, in its main form, is not simply the frame at its narrowest, and neither variant is announced as the pistol’s overall width.

So this directory records no overall width for the Shield Plus and publishes no width comparison. Note that Smith & Wesson’s own product page renders the same number under a plainer heading, “WIDTH,” which is exactly how the confusion propagates. Where a maker labels one figure two ways, the document whose purpose is specification governs — and that is the sheet, which uses the more careful label.

The honest conclusion is narrow and worth stating plainly: these two pistols may well be near-identical in width, and the published figures do not establish it.

Height and weight do not compare either.

Height fails on measurement basis. Glock states the G43X’s 5.04 in is measured including the magazine; Smith & Wesson states no magazine condition for the Shield Plus’s 4.6 in. The gap looks substantial — 11 mm — but it is a gap between two figures that were not measured the same way, so no delta is published.

Weight fails differently: there is no field the two records share. Glock publishes 16.40 oz without a magazine and 18.70 oz with an empty one. Smith & Wesson publishes a single 17.9 oz, states no magazine basis, and lists magazine weights separately — 2.6 oz for the 13-round, 2.2 oz for the 10-round. Those separate figures invite the reader to do arithmetic and reach a without-magazine number, and this directory does not do it: reading a field’s meaning off a neighbouring row is inference, not transcription. The magazine weights are recorded on the record so a reader can see exactly what is and is not established.

Two warranty structures, and one of them is easy to overstate.

Glock’s listed term is one year from original purchase by the initial consumer, with regional terms applying. Smith & Wesson’s is two policies rather than one, and collapsing them into “lifetime warranty” would merge two documents’ worth of distinct terms.

The first remedies defects notified in writing within one year of purchase by the original owner. A separate Lifetime Service Policy then begins when that year expires, repairing functional defects for the lifetime of the original owner on any Smith & Wesson handgun bought on or after February 1, 1989 — conditional on returning the Product Registration Card within 30 days, and expressly excluding the finish, grips, magazines and sights. Both are recorded on the record; neither is flattened into the other.

What the data supports—and what it cannot.

The sources settle overall length, barrel length, capacity, ignition on one side, trigger pull on the other, and both warranty structures. They do not settle width, height, or weight across this pair, and they cannot settle concealment, handling, reliability, or suitability for any lawful use. Three of the six dimensional rows carrying no delta is unusual, and it is reported here rather than papered over with numbers the sources do not support.

One asymmetry is a genuine gap rather than a mismatch: Smith & Wesson publishes no year introduced that this directory will use. The product record embeds a 2022-12-07 timestamp, but that is when the SKU’s entry was created on the commerce platform, not when the Shield Plus line launched, so the field is left empty. Glock’s 2019 for the G43X comes from a dated launch release.
