S&W Equalizer TS vs M&P 9 Shield Plus Optics Ready

By Cole Harlan, EditorUpdated Nov 5, 2026How we verifyEditorial standards

The biggest printed difference is the capacity ceiling: Smith & Wesson lists 10, 13 and 15 rounds for the Equalizer TS (SKU 13591) and 10 and 13 for the Shield Plus Optics Ready (SKU 13534). The Equalizer lists an internal-hammer-fired action and a grip and thumb safety; the Shield Plus lists striker fired and no safety. Every figure is copied from S&W’s own product pages, checked November 5, 2026.

Like for like: the two pages label the same measures differently. The Equalizer page prints “length,” “height” and “width” as plain figures; the Shield Plus page prints “overall length,” “overall height” and “width” in its description. Neither page says whether height or weight includes a magazine, so we do not subtract or rank them. Barrel length is published as “3.675” and “3.1” without a unit on the custom field, which we copied as printed. A dash means the page we read prints no value. S&W prints a price on each page; we list none.

Which to pick (on paper)

If the capacity ceiling is the deciding number: S&W lists 10, 13 and 15 for the Equalizer TS and 10 and 13 for the Shield Plus Optics Ready.
If barrel and overall length are the deciding numbers: the Equalizer lists a 3.675 barrel and 6.75 in length; the Shield Plus lists 3.1 and a 6.1-inch overall length.
If the action type matters to you: S&W labels the Equalizer INTERNAL HAMMER FIRED and the Shield Plus STRIKER FIRED. We have not tested the triggers.
If a manual safety matters to you: S&W lists a GRIP & THUMB safety on the Equalizer and NONE on the Shield Plus.
If you want the lower printed weight: S&W lists 19.3 oz for the Shield Plus and 22.9 oz for the Equalizer, with no magazine state given on either page.
If you plan to mount a red dot: both pages print OPTIC READY YES. The page data does not name a footprint here, so check our pistol red dot footprints guide and S&W before you buy an optic.

Magazines

S&W’s “Level Up: The Equalizer” article, which is embedded in the Equalizer TS product page we read, says the Equalizer comes with “three included magazines carrying 10+1, 13+1, and an all new 15+1 capacity” and that “These magazines are completely interchangeable with the M&P®9 Shield™ Plus.” That is S&W marketing text about the Equalizer and the Shield Plus by name; it does not name SKU 13534, the Shield Plus page we read does not repeat it, and we have not tested it.

We have not range-tested these; facts above are from the makers.
