Available now at $369 — well below the $399 MSRP — it’s one of the best values in the handgun market right now.

Key Features of the Springfield Armory XD Mod.4

Springfield Armory didn’t just slap an optics cut on an old frame and call it a day. The XD Mod.4 represents a genuine evolution of the XD platform, touching nearly every component that matters to a serious shooter. Let’s walk through what makes this pistol stand out in a crowded field of semi-automatic pistols.

Factory-Milled Optics Cut: The slide on the XD Mod.4 comes from the factory with a precision-milled optics cut that accepts three of the most popular red dot footprints on the market — the Trijicon RMR, Leupold DeltaPoint Pro, and Docter. This isn’t an afterthought; it’s integrated into the slide’s design, keeping the optic as low as possible for a natural sight picture. The cut comes with optic adapter plates included in the box, so you don’t have to spend extra to mount your preferred optic immediately.

Redesigned Flat-Face Trigger: One of the most talked-about upgrades in the Mod.4 is the flat-face trigger. Springfield’s engineers reworked the geometry to provide a more consistent finger placement shot to shot, which translates to improved accuracy, especially for shooters coming from striker-fired platforms. The trigger breaks cleanly, with a short reset that rewards practiced hands.

Melonite-Coated Barrel and Slide: The 4-inch steel barrel and steel slide both receive Springfield’s Melonite treatment — a ferritic nitrocarburizing process that creates an exceptionally hard surface layer. Melonite outperforms traditional bluing in corrosion resistance and wear resistance, making the XD Mod.4 a smart choice for duty use, range training, or any environment where your gear takes abuse.

16+1 Capacity: The XD Mod.4 ships with a 16-round stainless steel magazine — giving you 16+1 rounds of 9mm Luger on tap. That’s a meaningful advantage over traditional carry pistols, and it positions the XD Mod.4 competitively against other full-size 9mm handguns in its class.

Safety Features: The XD platform has always been known for its layered passive safety system, and the Mod.4 continues that tradition. You get a grip safety that must be fully depressed for the pistol to fire, a loaded chamber indicator (tactile — you can feel it in the dark), and a striker status indicator on the rear of the slide so you always know the pistol’s status at a glance. These aren’t gimmicks; they’re practical features for anyone who carries or stores a loaded firearm.

Sights: Out of the box, the XD Mod.4 wears a red fiber optic front sight paired with a white dot rear — a combination that’s fast in bright conditions and gives you enough contrast for accurate shots at defensive distances. If you’re mounting an optic, these co-witness well with most red dots.

Who Is the XD Mod.4 For?

If you’re in the market for a full-size 9mm pistol that can go from the nightstand to the range to the field without skipping a beat, the XD Mod.4 deserves a hard look. Home defenders will appreciate the 16+1 capacity, the layered safety system, and the optics-ready slide — mounting a red dot on your home defense pistol is no longer a luxury, and Springfield has made it straightforward. The included optic plates mean you’re not hunting for adapters before you can run your preferred optic.

Competitive shooters and range enthusiasts stepping up from a budget pistol will find a lot to like here. The flat-face trigger provides a consistent pull that rewards dry-fire practice, and the fiber optic front sight is genuinely fast in competition lighting. At $369 — or $349 during the current sale — you’re getting features that would cost significantly more on a custom-tuned pistol. For IDPA or USPSA Production division, the XD Mod.4 checks nearly every box without requiring expensive modifications.

Law enforcement officers and armed professionals looking for a duty-rated backup or off-duty carry gun will appreciate the Melonite-coated barrel and slide — a finish proven to hold up in harsh environments. The XD platform has a long history in law enforcement holsters, and the Mod.4 upgrades make it more capable than its predecessors.

Frequently Asked Questions

Q: Is the Springfield Armory XD Mod.4 a good pistol? (XD Mod.4 review)
A: Yes — the XD Mod.4 is a strong performer backed by Springfield Armory’s proven XD platform. The factory optics cut, flat-face trigger, and Melonite finish are meaningful upgrades that put it ahead of older XD variants. It’s not the flashiest pistol on the market, but it’s well-built, reliable, and priced to compete. Most reviews highlight the value proposition: you’re getting optics-ready capability for under $400, which is difficult to beat at this price point.

Q: XD Mod.4 vs Glock 19 — which should I buy?
A: Both are excellent full-size 9mm pistols, but they’re not identical. The XD Mod.4 offers more capacity (16+1 vs. 15+1 for the Glock 19 Gen 5 MOS), a factory optics cut on all models, and a grip safety that some shooters prefer. The Glock 19 has a larger aftermarket, lighter weight (23.63 oz vs. 27 oz), and arguably a simpler manual of arms (no grip safety). If you already have Glock magazines and accessories, that ecosystem has value. If you’re starting fresh, the XD Mod.4’s included optic plates and lower price point make it an attractive alternative.

Q: What optics fit the XD Mod.4? (XD Mod.4 optics)
A: The XD Mod.4 comes with a factory-milled cut that accepts three footprints out of the box: the Trijicon RMR, Leupold DeltaPoint Pro, and Docter. Adapter plates are included in the box. Popular red dot choices include the Trijicon RMR Type 2, Leupold DeltaPoint Pro, and the Holosun 507C (using an adapter). Springfield’s optics cut keeps the dot as low as possible for a natural sight picture — an important consideration for shooters who run both irons and optics.

Q: How reliable is the XD Mod.4? (XD Mod.4 reliability)
A: The XD platform has a decades-long track record of reliability across law enforcement and civilian use. The Mod.4’s Melonite-coated barrel and slide contribute to long-term durability, and the gun is designed to function with a wide range of 9mm ammunition — from 115gr FMJ range fodder to 147gr defensive loads. Field reports and professional reviews consistently rate the XD Mod.4 as highly reliable across thousands of rounds with minimal maintenance. As with any firearm, an initial break-in period of 200–300 rounds is recommended.

Q: What is the price of the Springfield Armory XD Mod.4? (XD Mod.4 price)
A: The XD Mod.4 Optics Ready has an MSRP of $399.00. We currently have it in stock at $369.00, with a sale price of $349.00 running through April 7, 2026.
