Springfield Armory has released the Echelon 4.0FC Comp 9mm pistol that pairs a full-size grip module with a compact slide and an integral compensator. The serialized Central Operating Group is made of stainless steel and can be transferred between grip modules. The Variable Interface System allows more than 30 optics to mount directly to the slide without adapter plates.

A 4-inch barrel and the compensator reduce muzzle rise, with the front sight set behind the compensator. The ambidextrous pistol includes tritium and luminescent U-Dot sights, a 17-round flush magazine and a 20-round extended magazine at an MSRP of $784, plus 15-round and 10-round versions for restricted locales along with Gear Pac and FIRSTLINE models.
