Overview
Built for full-size 9mm duty use, this pistol pairs Springfield Armory’s serialized Central Operating Group with a polymer frame to support a modular setup in a straightforward, service-oriented package. The 4-inch barrel and striker-fired action are aimed at consistent performance, while the black Melonite finish and integrated trigger safety add practical durability and control. It is optics ready and comes with an Aimpoint COA, along with two magazines in 17- and 20-round capacities, making it well suited for range work, training, or defensive carry where a larger pistol is preferred. The fixed sight setup with a luminescent front and Tactical Rack U-Dot rear gives it a simple, usable sight picture without unnecessary complexity.

Considerations & Trade-offs
- Full-size frame and 4-inch barrel make it less compact for concealed carry or minimalist pack use.
- The optic-ready setup is paired with an Aimpoint COA, so buyers who prefer iron-sight-only carry may be paying for a feature they do not plan to use.
- Magazine capacity is listed as 20+1, but the included magazines are 17-round and 20-round, so loadout may vary by magazine choice.
- As a striker-fired pistol with trigger safety, it offers a straightforward manual of arms, but it does not add a manual thumb safety for users who prefer one.
