There’s no arguing that Smith & Wesson M&P Shield, the compact striker-fired polymer pistol, is popular—the company has sold more than 1 million of the guns in just the few years since it was introduced, making it one of the company’s most popular models.

One of the first things those million-plus owners want to upgrade at some point is the Shield’s factory trigger. Thanks to Apex Tactical Specialties, a company known for its fire control system upgrades for a variety of S&W pistols, Shield owners can make the upgrade themselves with their drop-in trigger units.

According to this post from the Outdoor Wire, the kits directly replace the M&P Shield’s factory hinged trigger with a solid aluminum trigger body using a center-mounted pivoting safety that maintains factory safety values, the story says.


The company’s action enhancement reduces pre-travel and over-travel by about 20 percent. The Duty/Carry Kit provides a smooth, consistent trigger pull about 2 pounds lighter than the factory bang switch, with a more detectable trigger reset, the story says.

“Our kits for the M&P Shield are among the most popular we offer. In fact, at last year’s NRA Show in Nashville, we sold out of Shield kits halfway through the show. Regardless of which option customers go with, nearly all find the Apex upgrade to be a night and day difference over the factory trigger,” said Scot Folk, Vice President of Apex, in the story.

Apex makes three different trigger upgrade kits for the Shield: the Action Enhancement Trigger (MSRP: $159.95), the Red Anodized Action Enhancement Trigger ( (MSRP: $164.95), and the Flat-Faced Action Enhancement Trigger ($164.95). Those prices include the Duty/Carry Kit with each, but they can also be purchased separately.

The M&P Shield is a polymer, striker-fired pistol, designed for concealed carry and available in 9mm or .40 S&W. It also comes in a variety of grip lengths and capacities. See a history of the pistol here and details about the latest model here.
