Thompson Center Contender G1 .45 Colt/.410 12-Inch Single-Shot Pistol
This G-prefix Thompson Center Contender G1 pairs a versatile 12-inch .45 Colt/.410 vent-rib barrel with the platform’s famous interchangeable-barrel frame. Built in the United States and no longer in production, the G1 series is prized for its rugged blued-steel construction, smooth break-action, and quick hammer-selector that lets the shooter swap between rimfire and centerfire barrels. Walnut furniture with finger-groove grip and matching fore-end rounds out a classic configuration collectors and hunters alike appreciate.

What’s Included
- Choke tool
The factory 12-inch barrel is rifled for .45 Colt accuracy yet accepts 3-inch .410 shotshells; a removable choke improves shot patterns when using .410. A raised vent rib and bead front sight aid rapid target acquisition, while the screw-adjustable rear sight allows precise zeroing.
The break-open action locks solidly, and the external hammer incorporates a pivoting selector marked C/R, giving the shooter instant control over centerfire or rimfire firing pins when swapping barrels. This hallmark Contender feature underpins the platform’s celebrated adaptability.
Deep blued steel throughout provides classic aesthetics and durable protection. The walnut finger-groove pistol grip and matching fore-end offer a secure, comfortable hold and maintain the pistol’s traditional look.
With its discontinued G1 frame, G-prefix serial number, and factory .45 Colt/.410 barrel, this Contender stands out as both a practical field gun and a collectible example of Thompson Center’s pioneering single-shot design.
