Key Takeaways The Echelon Pro Comp runs a 4.5-inch barrel with an integrated V-shaped compensator — same overall size as a Glock 17, with a full-size grip. Springfield's new optic system mounts red dots directly to the slide using swappable pins — no plate for Trijicon RMR or Leupold DeltaPoint Pro footprints. GoldenWebb confirmed the optic held zero with zero play after 500 rounds, and backup irons remain visible through the optic window. 124-grain 9mm is his top pick for this compensator, followed by 147-grain, then 115-grain.
