1911 Slide Bore Gauge Kit – Precision Pin Gauges

TMC 1911 Slide Bore Gauge Kit – Measure with Precision and Confidence

Upgrade your 1911 build or maintenance routine with the TMC Slide Bore Gauge Kit. With this kit, you can quickly and accurately determine your slide opening size. Consequently, you will select the correct barrel bushing without guesswork. Furthermore, this kit simplifies measurements compared to calipers, making your work faster and more reliable.

High-Quality Pin Gauges for Accuracy

The kit includes four American-made pin gauges. Each pin is CNC-machined from hardened tool steel and rated at 60/65 Rc for long-lasting durability. In addition, each pin features a smooth 10-microinch finish. This ensures that it glides easily into the slide, without scratching or damaging your parts. Moreover, the pins are marked with both diameter and tolerance direction, which makes identification quick and easy.

Precise Sizes and Consistent Results

The four included pin diameters measure the most common slide bore openings: .699, .701, .703, and .705 (minus). Each pin measures 2 inches in length and maintains roundness within .0001″ (0.0025mm). Therefore, you can rely on the pins for consistent, professional-level accuracy. Additionally, this level of precision reduces errors when building, repairing, or maintaining your 1911.

Organized and Protected

All pins come in a foam-lined storage case. As a result, your gauges stay protected from dust, debris, or damage. Furthermore, the case keeps your tools organized and ready for immediate use, whether at home or in the shop.

Whether you are building a custom 1911, performing routine maintenance, or replacing worn parts, the TMC Slide Bore Gauge Kit saves time, improves accuracy, and guarantees consistent results.
