Wilson Combat 703G18 Full Size Recoil Spring #18 - Chrome Silicone Steel

The Wilson Combat 703G18 Full Size Recoil Spring #18 is a Chrome Silicone Steel replacement spring engineered for 1911 pistols chambered in .45 ACP. Whether you're running a full-size 1911 for competition, duty, or precision shooting, a quality recoil spring is one of the most critical wear items in your gun—it governs reliability, felt recoil, and longevity of your frame. Wilson Combat springs are machined to exacting standards and built to handle thousands of cycles without degradation, making them a trusted choice for shooters who demand consistency.

The #18 designation indicates the spring rate (in pounds of pressure), matched to full-size 1911 platforms. Upgrading to a fresh factory spring when you notice increased muzzle flip, sluggish cycling, or an older gun showing its age can restore your 1911 to like-new performance. Chrome Silicone Steel construction resists corrosion and fatigue, so your spring maintains its characteristics cycle after cycle.

If you're rebuilding a 1911, performing preventive maintenance, or replacing a worn component, this is the kind of OEM-quality part that belongs in your rebuild kit. Wilson Combat's reputation in the 1911 community is built on attention to detail, and their springs reflect that commitment to reliability.

Frequently Asked Questions

Is this spring compatible with my 1911 full-size model?

The Wilson Combat 703G18 is designed for full-size 1911 platforms chambered in .45 ACP. If you own a full-size 1911 in that caliber, this spring should fit; however, always verify compatibility with your specific model before ordering, or reach out to our team.

When should I replace my 1911 recoil spring?

Recoil springs are wear items that degrade over time and thousands of rounds. Signs of a worn spring include increased felt recoil, sluggish slide cycling, or failure to lock back reliably. Many shooters replace their springs proactively every few years or after 5,000–10,000 rounds as preventive maintenance.

What does the #18 rating mean?

The #18 denotes the spring rate—how much force (in pounds) it takes to compress the spring. Wilson Combat's #18 is engineered for standard full-size 1911 pistols and is among the most common rates for that platform.
