TMC STI / 2011 Magwell

TMC STI / 2011 Magwell – Precision CNC Aluminum Magwell for Gen 1 2011 Grips

Upgrade your STI or 2011 pistol with the TMC STI / 2011 Magwell, a precision-engineered enhancement designed to deliver faster reloads, improved handling, and a more competition-ready feel. Because it’s CNC-machined from a high-quality aluminum alloy, this magwell offers a strong, lightweight design that boosts performance without adding unnecessary bulk.

Fast, Reliable Reloads

The TMC Magwell features a perfectly contoured funnel that dramatically speeds up magazine changes. As a result, shooters gain smoother reloads and more consistency during competition, training, or tactical use. Its optimized opening guides magazines directly into the grip—even under stress—making every reload quicker and more reliable.

Durable CNC-Machined Aluminum Construction

Crafted from a premium aluminum alloy, the TMC Magwell combines strength and low weight. The CNC machining process ensures clean edges, a precise fit, and a refined appearance. Despite its light weight, the magwell provides excellent durability for both range sessions and hard-use environments.

Easy, No-Modification Installation

Installation is simple and fast. The TMC Magwell fits all STI / 2011 Gen 1 style grips without any frame or grip modification. Additionally, it includes a black mainspring housing pin, so you have everything needed for a clean, secure install. Slide the magwell into place, secure the pin, and you’re ready to shoot.

Enhanced Balance & Control

The lightweight design maintains ideal pistol balance, keeping the gun fast and controllable during transitions. Moreover, the smooth exterior and comfortable contouring help the magwell blend naturally into the grip, offering an improved hand position without interfering with your draw.
