This Cloak Shell is molded for the Springfield Echelon, locking onto its modular frame, full-length rail, and aggressive slide cuts with precise retention. Built around the Echelon’s 4.5-inch barrel and billet-like slide profile, the shell captures the full-size footprint without adding unnecessary bulk, maintaining tight tolerances around the squared trigger guard, ejection port, and optic-ready top end. Suppressor-height sight channels remain unobstructed, and the open muzzle accommodates threaded barrels or future upgrades. Formed from rigid Boltaron, this shell resists flex, cracking, and heat warping under daily carry stress. Whether running the Echelon IWB for concealed defense or OWB for duty applications, the Cloak Series base system stabilizes the pistol’s weight through a padded, body-conforming platform. The shell’s passive retention system locks into the Echelon’s deep slide serrations and undercut guard, delivering a clean draw without drag. This shell works only with Cloak Series holster bases and does not support ShapeShift hardware. Due to post-2015 modular split, revolver shells are not cross-compatible. Springfield Echelon owners already using Cloak Series platforms can drop in this shell, fine-tune retention, and deploy their pistol with a rig built for consistency, carry comfort, and hard-use reliability.
