Wilson Combat 10G18 Recoil Spring 10mm/45 ACP 1911 Full Size

The Wilson Combat 10G18 Recoil Spring delivers consistent cycling and enhanced reliability for full-size 1911 pistols chambered in 10mm Auto and .45 ACP. This precision-manufactured spring addresses the unique recoil characteristics of these powerful cartridges while maintaining proper slide velocity and timing.

What Makes This Different

Wilson Combat engineers this spring with specific wire diameter and coil tension to handle the increased bolt thrust of 10mm Auto cartridges while remaining compatible with standard .45 ACP loads. Unlike generic replacement springs that often cause cycling issues with high-pressure rounds, the 10G18 maintains consistent compression rates across temperature ranges. The spring's 18-pound rating provides optimal balance between reliable ejection and controlled slide return.

Key Features

• 18-pound spring rate optimized for 10mm Auto and .45 ACP cartridges
• Chrome silicon wire construction resists compression set and fatigue
• Precision wound coils ensure consistent spring tension throughout service life
• Compatible with Government Model and Commander length 1911 frames
• Heat-treated construction maintains spring properties under rapid fire
• Direct replacement for factory recoil springs in full-size 1911 pistols
• Manufactured to Wilson Combat's match-grade tolerances

Competition shooters and law enforcement officers rely on this spring's consistent performance during extended shooting sessions. The 10G18 maintains proper slide timing with both light target loads and full-power defensive ammunition, reducing the need for spring changes when switching between load types. Field testing demonstrates reliable cycling with bullet weights from 165 to 230 grains in 10mm, and 185 to 230 grains in .45 ACP.
