Description
When it comes to home defense or a reliable truck gun, you need a platform that’s simple, robust, and ready to go. The Just Right Carbines Gen3 Takedown Marine 45 ACP 17″ Electro-less Nickel Finish, 13rd Glock Compatible Magazine is a takedown carbine chambered in .45 ACP. It features a corrosion-resistant marine finish, uses readily available Glock magazines, and breaks down for easy transport and storage—all for a price of $755.94.
Here’s the thing—a home defense firearm needs to be dependable in a high-stress moment. This carbine delivers that. The .45 ACP round offers proven stopping power, and the 17-inch barrel provides better ballistic performance and control than a handgun. The electro-less nickel finish isn’t just for looks; it’s a hard, non-reflective coating that shrugs off moisture, sweat, and fingerprints, making it ideal for humid Missouri summers or secure storage. At 6.5 pounds unloaded, it’s substantial enough to be steady but not a burden.
Key Features
The takedown system is the core of this carbine’s practicality. A simple push of a button allows you to separate the barrel and handguard from the receiver in seconds. This means the entire package fits into a compact, discreet case or backpack. No gunsmithing required to assemble or disassemble. When you need it, it goes together just as fast. The 13-round magazine capacity gives you a solid reserve, and compatibility with Glock 21 magazines means you have a vast ecosystem of affordable, reliable spares and higher-capacity options available.
The Gen3 platform incorporates ambidextrous controls, including a safety and magazine release, making it adaptable for left or right-handed shooters. The monolithic top rail is ready for optics, and the M-LOK compatible handguard lets you add lights or grips to suit your setup. It’s a modern, modular system built on a simple blowback operation that’s known for its reliability. The overall length is 35.5 inches when assembled, but it stores like something much smaller.

Frequently Asked Questions
Q: What Glock magazines does this carbine use?
A: It is designed to work with standard Glock 21 .45 ACP magazines. The included magazine is a 13-round unit, but it will also accept factory Glock 21 magazines of various capacities, where legally permissible.
Q: How difficult is the takedown process?
A: It is extremely simple. Push the takedown button located near the front of the receiver, rotate the handguard, and separate the barrel assembly. Reassembly is the reverse—no tools are needed, and it takes mere seconds once you’re familiar with the process.
Q: Is the finish durable?
A: Yes. The electro-less nickel plating is a technical process that creates a very hard, uniform, and non-porous layer that is highly resistant to rust, corrosion, and wear. It far surpasses typical blued finishes in protective quality, hence the “Marine” designation.
