S&W M&P Shield Plus: 13+1 at Single-Stack Width

Smith & Wesson took the most-carried pistol in America and gave it the capacity it was missing. Here's what to know before you buy one.

Condition One, the DefensiveHandgun.com journalPublished Sep 22, 20267 min read
The short answer

The Shield Plus is a safe, sensible carry pistol: it keeps the slim Shield frame that made the original popular, adds a 13-round magazine and a much better trigger, and sells with or without a thumb safety. Pick the no-safety version unless you specifically want one, buy the optics-ready slide if a dot is in your future, and expect it to be the pistol you recommend to a first-time carrier.

What the Plus Changed

The original M&P Shield sold in enormous numbers because it was thin, reliable, and cheap to feed. Its limits were a 7 or 8-round single-stack magazine and a hinged trigger nobody loved. In 2021 the Shield Plus kept the slim frame and slide, widened the magazine well just enough for a stack-and-a-half magazine (10 or 13 rounds), and replaced the trigger with a flat-face design that breaks cleanly. Same holsters, roughly the same width, nearly double the capacity of the first Shield.

The Thumb-Safety Decision

The linked listing includes the manual thumb safety, per the listing. S&W sells the Shield Plus both ways, and the choice is personal. A thumb safety adds a step to the draw that must be trained until it's automatic; it also reassures some carriers, especially those who pocket-carry or carry off-body. If you've never trained with one, the no-safety version is simpler. If you have, the Shield's safety is small and stiff enough that it won't disengage in a holster. Either way, the pistol still has a trigger safety and a striker block.

Shooting It

The Shield Plus is easy to shoot for its size because the grip, while slim, is long enough with the 13-round magazine for a full hold, and the flat trigger has a short, distinct reset. Recoil is snappy in the way every 3-inch 9mm is snappy. Sights are white three-dot on the base model, adequate and easy to replace. The easy-rack guide notes that the Shield family's slide is on the stiffer side; if that's a concern, S&W's Shield EZ line, covered in the Shield EZ 9mm review, is the answer.

The Pick and Two Alternatives

1

Smith & Wesson M&P9 Shield Plus, thumb safety

The pick

9mm · 3.1 in · 10 and 13-round magazines, per listing

Slim, proven, and better than the original in the two places that mattered. The listed configuration includes the thumb safety; S&W sells no-safety and optics-ready versions if either matters to you.

2

Canik Mete MC9 9mm

More capacity, more gun

9mm · 15+1 per listing · optics-ready

The MC9 gives you 15 rounds, an optic cut, and Canik's trigger for similar money, in a slightly wider frame. Our MC9 review covers it in full; it's the pistol to choose if capacity beats slimness for you.

3

Taurus G3XL 9mm

Budget

9mm · 4 in · 12+1

A 4-inch slide on a compact grip at the bottom of the price range. Wider than the Shield and not optics-ready, but soft-shooting and accurate. The G3XL review has the details.

Setting It Up

Optics-ready or not. The linked SKU is not optics-ready. If you want a red dot now or later, buy the Shield Plus OR version, which is cut for a micro-footprint dot; milling a standard slide later costs more than the difference. See the red-dot carry guns guide.

Who It's For

The Shield Plus is the pistol for someone who wants a slim, proven 9mm with real capacity and a trigger they won't have to apologize for, from a maker with a service department. It's the default recommendation in the beginner's guide for a reason, and it sits comfortably in the micro-compact 9mm class against the P365 and Hellcat.

Without, unless you've trained with one or specifically want it for off-body or pocket carry. The listed SKU includes the safety; S&W sells both.

Do original Shield holsters fit the Shield Plus?
