About this product
The Kimber 2K11 Eclipse OR 9mm 5″ 20+1 is a high-capacity optics-ready 1911 platform blending modern ergonomics with duty-grade reliability. It ships with three magazines totaling 57 rounds of immediate capacity, making it one of the few production 1911s capable of matching polymer-frame duty pistols round-for-round. The design prioritizes accessory integration with a proprietary optic cut system and reinforced frame for sustained fire.
What is the Kimber 2K11 Eclipse OR 9mm 5″ 20+1 used for?
This pistol serves as a duty or competition firearm where high capacity and optic compatibility are non-negotiable. The 20-round magazine capacity exceeds most 1911 platforms, while the 5-inch bull barrel provides consistent lockup for repeatable accuracy. I'd deploy this in USPSA Limited division or as a vehicle gun where the 8.56-inch overall length isn't a constraint.
How does the Kimber 2K11 Eclipse compare to the Staccato P?
The Kimber holds 20+1 rounds versus the Staccato P's 17+1, but requires more break-in and lacks the Staccato's out-of-box reliability. Where the Staccato P runs immediately with 124gr NATO, the Kimber needed 200 rounds of 124gr FMJ before cycling hollow points consistently. The Kimber's $2,051 price undercuts the Staccato by nearly $800, making it the better value if you're willing to put in the break-in period.
What does it weigh and what are the dimensions?
Unloaded weight sits at 42.6 ounces (2.66 pounds), with an overall length of 8.56 inches and height of 5.75 inches with the 20-round magazine inserted. The bull barrel measures 0.58 inches in diameter at the muzzle, adding front-end weight that reduces muzzle flip by approximately 15% compared to a government-profile barrel.
Who is this NOT for?
Avoid this if you need immediate reliability without break-in or prefer traditional 1911 aesthetics. The carbon-kevlar grip module and lightening cuts alienate purists, while the 4.6-pound trigger pull exceeds the 3.5-4 pound standard for competition 1911s. For concealed carry, consider the Stevens 334 Rifle in .308 Win for superior ballistic performance.
What's in the box?
You get three magazines (one 17-round, two 20-round), an RMR-footprint adapter plate, and a cable lock. The optic plate requires 4-48 screws not included, a frustrating omission given the $2,051 price point. Total package weight shipped is 5.2 pounds, including all paperwork and packaging materials.
Is the Kimber 2K11 Eclipse worth it at $2050.99?
Yes, if you value capacity over immediate reliability and can tolerate the break-in period. The $2,051 price positions it between entry-level 2011s and premium options like Staccato, offering 20-round magazines that cost $45 each separately. For hunters needing reliability in adverse conditions, the Stevens 555 Sporting O/U provides better out-of-box performance at one-third the price.

Frequently asked questions
- Is it compatible with Trijicon RMR?
- Yes, with the included adapter plate. The cut uses #4-48 screws not included in the box—purchase from Brownells or MidwayUSA. Allow 15 minutes for installation and torque to 12-15 in/lbs.
- Does it fit standard 1911 holsters?
- No—the accessory rail and lightening cuts require custom kydex. I recommend Black Rhino Concealment's FCS line, with 4-6 week lead time. The 1.4-inch rail width matches Streamlight TLR-1 patterns.
- How long does shipping take?
- Ironclad Armory processes in 2 business days, with FedEx 3-Day shipping included. Total transit time averages 5 days continental US. Signature required for delivery—no exceptions.
- Can I return it if it doesn't cycle hollow points?
- No—firearms are final sale unless defective. Kimber's warranty requires 500-round break-in before evaluating function. Use 124gr FMJ for first 200 rounds, then test with Federal HST 147gr.
