Springfield's modern duty pistol is built around a removable fire control unit that can move between frames. It is a striker-fired 9mm with an optic-ready slide, and the design aims to compete directly with the best polymer pistols on the market. Many shooters say the grip feels natural and the trigger is crisp.

This used Echelon comes with two magazines, the factory box, and a range bag. The bag is a nice extra, since it gives you somewhere to keep the pistol, the magazines, and the ammunition you plan to shoot. Check the photos for the exact configuration and sights.

The optic-ready slide is worth mentioning. If you plan to add a red dot, check what plate system the pistol uses and confirm that it fits the optic you have in mind. Springfield designed the Echelon to take many common footprints, which saves you from buying a dedicated slide.

Treat a used pistol with the usual checks. Run the slide by hand, test each magazine, and look at the barrel crown and the chamber. Fire a few boxes of ammunition before you rely on it. It is sold as described, in used condition. The pistol ships to your local FFL dealer for the background check.
