Description
The Kimber KHX Custom (OI) 9mm 5-inch 9+1 stainless slide is a factory-optics-ready handgun that ships with a Holosun HE507C-GR-X2 green-dot sight already mounted. This isn’t a project gun you have to finish—it’s a complete EDC rig with front-strap stippling, G10 grips, and a KimPro II gray finish that balances carry comfort with slide durability. The 5-inch barrel gives you a longer sight radius and a bit more velocity, while the 9+1 capacity keeps it slim enough for daily carry. If you want a 1911-style 9mm that’s ready to run out of the box, this is it.

Key Features
- Factory-Milled Optic Cut (OI) – The slide is machined from the factory to accept Holosun/RMR-pattern red dots, so you don’t need aftermarket milling or a plate. The included Holosun 507C-GR-X2 gives you a 32 MOA ring and 2 MOA dot in one window. Why it matters: you get a pro-level optic setup without paying extra or waiting on a gunsmith.
- Front Strap Stippling – The grip frame has aggressive stippling on the front strap, giving you a locked-in hold even with sweaty hands or in a hurry. Why it matters: no slip, no readjustment, just consistent purchase on every draw.
- KimPro II Gray Finish – This multi-layer coating on the stainless slide resists rust and holster wear better than standard bluing. Why it matters: your carry gun stays looking good after a year of daily sweat and friction.
- G10 Grip Panels – Textured G10 panels provide a solid index point for your support hand while staying thin enough to not print under a T-shirt. Why it matters: you get traction without bulk.
- 5-Inch Barrel – The full-length 5-inch barrel gives you a longer sight radius for easier accuracy and a slight velocity bump over 4-inch guns. Why it matters: more hits on target at distance, and softer recoil impulse than shorter barrels.
Who It’s For
This Kimber is for the daily carrier who wants a 1911-pattern 9mm with a red dot, but doesn’t want to deal with aftermarket machining or mounting hassle. It’s also for shooters who prefer a full-size frame for range work, competition, or home defense but still want the option to carry it concealed. If you’re already running Holosun optics, this is plug-and-play.
Pros & Cons
- Pro: Ships with a quality Holosun green dot—no extra purchase needed.
- Pro: Factory stippling is aggressive enough to work but not rough on skin.
- Pro: 5-inch barrel balances accuracy and concealability better than most full-size 1911s.
- Con: The 9+1 capacity is standard for a single-stack 1911, but some shooters may want higher round count in a 9mm carry gun.

The Kimber comes in at a lower price than both competitors and includes a Holosun optic, making it a better value if you want a complete setup. The Zev OZ9 offers higher capacity but uses a polymer frame. The Agency AOS has a modular optic plate system but costs significantly more and doesn’t include a sight.
FAQ
Does the Kimber KHX Custom (OI) come with a red dot sight installed?
Yes. This specific model ships with a Holosun HE507C-GR-X2 green-dot optic already mounted and zeroed from the factory. You don’t need to buy or install anything extra.
What footprint does the optic cut use?
The slide is milled for the Holosun 507C/508T and Trijicon RMR footprint. If you want to swap optics later, any sight with that pattern will fit without a plate.
Is the stippling too aggressive for concealed carry?
The front strap stippling is aggressive enough to prevent slipping under recoil, but it’s not sharp enough to irritate your skin through a shirt. Most carriers find it comfortable for all-day carry.
What is the warranty on this Kimber?
Kimber offers a one-year warranty on parts and labor, plus a lifetime warranty on the frame and slide against defects. Check Kimber’s site for full terms.
Can I use +P ammunition in this pistol?
Yes. Per Kimber specs, the KHX Custom (OI) is rated for +P 9mm loads, though extended use of +P+ may accelerate wear. Standard pressure is recommended for daily carry.
