Key Features

• Officer-Style Grip with Commander Slide – Why it matters: You get a shorter grip that hides well under a vest or jacket, but the longer slide keeps the muzzle flip down and your sight picture steady, which matters on a dove field or in the woods.
• G10 Tactical Grips – Why it matters: These grips give you a secure hold even with sweaty hands after a long morning hunt, and they hold up to rain and mud without getting slippery.
• Button-Rifled Barrel with Full-Length Guide Rod – Why it matters: The button-rifling improves accuracy shot after shot, and the full-length guide rod helps the recoil spring cycle smoothly, reducing wear and keeping the pistol running reliably.
• Ambidextrous Thumb Safety – Why it matters: Whether you shoot left-handed or right-handed, this safety lets you carry cocked and locked with confidence, and it’s easy to sweep off quickly when you need it.
• Skeletonized Hammer and Trigger – Why it matters: The lighter hammer speeds up lock time, and the skeletonized trigger gives a crisp, clean break that helps you place shots where you aim them.

Who It’s For

This pistol is built for the southern shooter who carries a sidearm while walking fence lines, hunting doves over a field, or working a bird dog in thick cover. It’s also a good fit for anyone who appreciates a traditional 1911 platform but wants a more compact package for daily carry without giving up the .45 ACP punch.

Pros and Cons

• Pros: Compact grip for concealment, accurate button-rifled barrel, ambidextrous safety, corrosion-resistant finish, affordable price for a 1911.
• Cons: The 7+1 capacity is lower than some modern double-stack pistols, so you’ll want to carry a spare magazine for extended field use.

Frequently Asked Questions
