Springfield Armory XD Mod.4 OSP 9mm Pistol: Optics-Ready Performance at a Budget Price

April 8, 2026 News

Springfield Armory has officially released the XD Mod.4 OSP 9mm pistol, a modern update to its long-running XD striker-fired platform. Designed for today’s shooters, the new model combines optics-ready capability, enhanced ergonomics, and proven reliability—all at an MSRP of $399.

For buyers searching for an affordable optics-ready 9mm handgun, the XD Mod.4 OSP enters the market as a strong contender in the budget-friendly defensive pistol category.

Optics-Ready Slide for Red Dot Compatibility

The standout feature of the XD Mod.4 OSP is its factory-milled slide, built to accept popular micro red dot sights using a plate-based mounting system. This allows shooters to upgrade to a red dot-equipped pistol for improved target acquisition and accuracy. Optics plates are available separately through Springfield Armory.

Enhanced Grip and Ergonomics

Springfield has refined the frame design to improve handling and control. The aggressively textured polymer grip is strategically placed to maximize traction where it matters most. An undercut trigger guard and extended beavertail allow for a higher grip, helping reduce muzzle flip and improve follow-up shots.

Deep, aggressive front and rear slide serrations further enhance usability, making the pistol easier to manipulate in adverse conditions.

Built-In Safety Features

The XD Mod.4 OSP includes multiple passive safety features commonly sought in a concealed carry or home defense handgun:

Grip safety that disengages with a proper firing grip
Striker status indicator at the rear of the slide
Loaded chamber indicator for both visual and tactile confirmation

These features add an extra layer of confidence for both new and experienced shooters.

Sights, Trigger, and Accessories

The pistol features a flat-faced trigger designed for a consistent pull, paired with a red fiber-optic front sight and white-dot rear sight for fast sight alignment. Both sights are steel for added durability.

A MIL-STD-1913 Picatinny rail on the dustcover allows users to mount weapon lights or other accessories, making it suitable for defensive or duty use.

Capacity and Availability

The XD Mod.4 OSP 9mm ships with a 16-round stainless steel magazine, while a 10-round compliant version is available for restricted states. With an MSRP of $399, it positions itself as one of the more accessible optics-ready striker-fired pistols on the market.

A Modern Take on a Proven Platform

Originally introduced more than two decades ago, the XD series helped shape the modern striker-fired handgun market. The Mod.4 OSP builds on that legacy with updated features aimed at today’s shooters looking for performance, reliability, and value in a 9mm pistol.
