The 4.0-inch compact variant features an integral single-port compensator on a Melonite-treated steel barrel. The front sight is positioned behind the compensator port for a clear sight picture during use. U-Dot sights combine a tritium/luminescent green front with a serrated U-notch rear that includes a rack ledge.
The pistol is upgraded with an aluminum Sharps Bros billet grip module. Machined from 7075‑T6 and finished in anodized black, it provides a pronounced beavertail, replaceable textured grip panels, a 3-slot Picatinny rail, and an integral flared magwell. An OEM polymer Echelon grip module is also included off-gun.
Springfield’s Variable Interface System enables direct mounting of popular optics using self-locking pins and an optics cut with a cover plate when irons are preferred. The serialized Central Operating Group modular fire-control unit underpins the platform’s adaptability. The slide adds front and rear cocking serrations, a forward trench grasping surface, and ambidextrous slide-stop levers.
This striker-fired 9mm uses a flat-faced trigger with an integral trigger safety. Capacity is 17+1, and the pistol ships with one 17-round and one 15-round steel Echelon-compatible magazine. The overall presentation is completed by carry-friendly accessories and factory packaging noted above.
