EGW Mainspring Housing – Springfield Prodigy – Magwell Ready – Stainless Steel
A Purpose-Built Upgrade for the Springfield Prodigy
Upgrade your Springfield Prodigy with an EGW magwell-ready mainspring housing engineered to improve control, enhance balance, and deliver a more secure grip. From the start, this precision-machined stainless steel MSH focuses on shooters who demand durability, consistency, and a clean, professional fit—especially when running a magwell.
Stronger Construction, Better Balance
Many factory mainspring housings use lightweight materials, and in some cases polymer. As a result, shooters often notice reduced rearward balance and less traction during recoil. The EGW stainless steel mainspring housing directly addresses these issues. By adding weight at the rear of the pistol, it helps the gun settle into the hand, track flatter under recoil, and return to target faster.
At the same time, the crisp 25 LPI checkering increases grip stability without feeling harsh. Consequently, you gain better control during rapid fire, reloads, and high-round-count sessions.
Designed from the Ground Up for Magwell Use
Because this mainspring housing is truly magwell ready, EGW positioned the checkering and contours to align perfectly with compatible Prodigy magwells. Therefore, the magwell installs flush with no gaps, uneven edges, or visual mismatches. In addition, this precise geometry ensures reloads stay smooth, consistent, and predictable.
Precision-Machined Stainless Steel Durability
EGW machines this housing from a single piece of solid bar-stock stainless steel. As a result, it offers excellent resistance to cracking, deformation, and long-term wear. Unlike cast or polymer alternatives, this MSH stands up to hard training, competition use, and demanding environments.
Furthermore, the bead-blasted stainless finish provides a clean, matte appearance that resists scratches and blends well with stainless, two-tone, or Cerakoted frames. In short, it performs as good as it looks.
