Read 2026-09-22. The page says only compact-size Echelon models, not full-size. 4.0C is the compact. 4.0FC is the same 4.0" slide on the full-size grip, so it takes the compact spring. 4.5F, Comp, and Alpha are not named. The kit includes the guide rod. Loose springs do not fit the factory captured assembly. The Wix title spells Echelon as ECHELOL; the product heading spells it ECHELON.
