Tripp Research Super 9 .45 ACP 9-Round Upgrade Kit

Tripp Researh Super 9 Upgrade Kit – .45 ACP

The 1911 .45 ACP Super 9 – 9‑Round Upgrade Kit improves feeding reliability while increasing usable capacity. Instead of replacing your entire setup, this kit upgrades internal components to deliver smoother operation, more consistent lock‑back, and dependable performance.

Because it focuses on the most critical wear parts, this upgrade solves many common feeding and slide‑lock issues found in extended .45 ACP configurations.

Improved Spring Design for Reliable Function

At the core of this kit is a 17‑coil chrome silicon spring with a .048‑inch wire diameter. This spring provides strong, consistent tension throughout the entire cycle. As a result, rounds feed smoothly and the slide locks back correctly after the last shot.

In addition, chrome silicon resists fatigue far better than standard music wire. Therefore, the spring maintains its strength longer, even under heavy use.

Increased Capacity Without Compromise

Although designed to fit .45 ACP Government‑length 10‑round bodies, this upgrade delivers a reliable 9‑round capacity. By optimizing spring tension and follower movement, the kit increases reliability while still offering extended capacity.

Consequently, shooters gain confidence without sacrificing function.

Solves Common Feeding and Lock‑Back Issues

Many feeding problems start with weak or mismatched springs. This upgrade directly addresses those issues by restoring proper control over cartridge movement and slide engagement. As a result, users experience fewer nose‑dives, smoother chambering, and consistent slide lock on empty.
