Upgrade the grip and balance of your Springfield Prodigy with the Evolution Gun Works Mainspring Housing. Precision-machined from premium stainless steel, this fully checkered replacement part delivers superior traction and strategic weight distribution, transforming the factory plastic component into a durable, performance-enhancing accessory.
Key Features
- Fully checkered 25 LPI pattern provides exceptional grip texture for improved control during rapid firing and holster draws.
- Stainless steel construction machined from bar stock with a glass-beaded finish for corrosion resistance and a professional appearance that complements stainless Prodigy models.
- Angled ergonomic design optimizes hand positioning and adds rearward weight to help manage recoil and enhance overall firearm stability.
- Direct fit for Springfield Prodigy 1911-style platform, ensuring seamless installation without modifications.
Benefits for Shooters
The factory mainspring housing on many 1911-pattern pistols is lightweight polymer that contributes little to balance. This EGW upgrade adds purposeful mass in the grip area while the aggressive checkering prevents slippage, even in wet or gloved conditions. Shooters report more consistent grip pressure and reduced muzzle flip, supporting faster follow-up shots and improved accuracy on the range or in competition.
