Kimber 2K11 Eclipse 1911 Full-Size 9mm Optics Ready Pistol (MPN 3500071): Specs, Features, Use Cases, and Setup Tips

Kimber 2K11 Eclipse 1911 Full-Size 9mm Optics Ready Pistol: Full-Size Control, 9mm Speed, and RMR-Pattern Optics Capability

Introduction

If you want the shootability of a full-size 1911-pattern pistol but with modern high-capacity performance and red-dot readiness, the Kimber 2K11 Eclipse 1911 Full-Size 9mm Optics Ready Pistol (MPN: 3500071, UPC: 669278350714) is purpose-built for that lane. It pairs a 5-inch bull barrel and long sight radius with an optics-ready slide cut for RMR-footprint compatibility, plus high-capacity magazines (two 20-rounders and one 17-rounder) that make it immediately relevant for training, range work, and action-pistol style use.

The “Eclipse” package adds a two-tone look—silver slide over a black frame—along with carbon fiber/Kevlar grip panels for a secure, performance-forward feel.

Key Features and Specifications

Below is a consolidated, spec-focused breakdown of what matters most on the Kimber 2K11 Eclipse 1911 Full-Size 9mm Optics Ready Pistol.

Core configuration

  • Action / pattern: 1911-style, single-action semi-automatic
  • Caliber: 9mm Luger

  • Weight: approx. 35 oz (with empty magazine)

Optics-ready system

  • Footprint: RMR-pattern compatibility is specifically associated with this model’s optics-ready configuration.
  • Mounting approach: plate-based interface (so you can match optic families to the correct plate).

Sights

Pricing / availability (verification note) Retail pricing and inventory move quickly. As of a recent listing, this model has been advertised around the low-to-mid $2K range at a large U.S. retailer, with store-dependent inventory shown. (rangeusa.com)

Practical Applications

The Kimber 2K11 Eclipse 1911 Full-Size 9mm Optics Ready Pistol is best understood as a “do-a-lot” full-size shooter: fast enough to run hard, stable enough to shoot precisely, and modern enough to mount the optics and lights most people actually train with.

1) Range training and skill building

A 5-inch, full-size, steel-framed 9mm platform is a strong recipe for high-quality practice:

  • Long sight radius (if you stay with irons) helps you call shots and confirm sight alignment errors.
  • Bull barrel adds rigidity and typically contributes to consistent lockup feel.
  • 9mm ammunition is widely available and generally easier on the shooter than larger calibers, encouraging higher round counts per session.

2) Optics-ready performance (carry optics / training optics)

Red dots have become a mainstream training tool for both speed and accountability. With an RMR-pattern-ready setup, you can run popular optics families like:

  • Trijicon RMR-class optics
  • Holosun 407C/507C/508T/507Comp-class optics

Kimber’s own store offers a C&H plate specifically marketed for 2K11/1911 optics mounting with fitment covering the RMR/RMR HD/SRO and common Holosun “C” footprints. (store.kimberamerica.com)

Setup tip: If you choose an aftermarket plate that integrates a rear sight (for example, a “rear sight forward” plate), you may need a taller front sight to zero correctly—this is specifically called out by Dawson Precision for some Kimber 2K11 plate configurations. (dawsonprecision.com)

3) Home-defense-ready configuration

While many buyers pick this category primarily for range/competition, the features translate well to defensive staging:

  • High capacity (17/20-round mags included)
  • Optics capability for low-light aiming with a clear focal plane
  • Full-size control that helps keep rapid strings accountable

If your variant includes an accessory rail (some listings describe an integrated rail on this configuration), pairing a quality weapon light is an obvious next step for practical low-light identification.

4) Competition and “match-style” use

The combination of:

  • single-action trigger geometry,
  • full-size sight radius,
  • optics readiness,
  • and high capacity,

makes the Kimber 2K11 Eclipse 1911 Full-Size 9mm Optics Ready Pistol an attractive option for action pistol disciplines and “run it fast” range drills.

Expert Analysis

From a product-research and end-user setup standpoint, here’s what matters most when you’re deciding on (and configuring) the Kimber 2K11 Eclipse 1911 Full-Size 9mm Optics Ready Pistol.

Why the 5-inch bull barrel matters in real use

A bull barrel on a 5-inch, full-size platform typically does two things well:

  1. Adds muzzle stability for faster return-to-sight picture during strings.
  2. Supports consistency—especially noticeable when you’re tracking dot movement during recoil.

You’re not just buying “accuracy potential,” you’re buying how easy it is to shoot accurately at speed.

Optics plates: “it fits” vs. “it holds up”

Optics-ready is only as good as the plate interface. Plate choice is where many shooters either win (reliable, repeatable zero) or lose (loose screws, shifting zero).

  • Kimber sells a C&H plate option intended for the 2K11/1911 interface and multiple RMR-family optics. (store.kimberamerica.com)
  • Dawson Precision offers Kimber 2K11-specific plates, including RSF (rear sight forward) configurations, and explicitly notes front sight height requirements for some setups. (dawsonprecision.com)

Recommendation: If you plan to run high round counts, prioritize a plate system with robust engagement, correct screw length guidance, and a clear installation procedure. Dry-fit your parts and verify screw length so you don’t bottom out screws or bind the extractor plunger area (a common cause of avoidable issues across plate-mounted pistols).

Magazines and reload consistency

Including two 20-round magazines and one 17-round magazine out of the box is a meaningful value-add for a high-capacity 1911-style pistol—especially if you intend to train with reloads. The best way to validate your personal setup quickly:

  • Mark each magazine (paint pen or basepad labels)
  • Run controlled failure testing (e.g., last-round slide lock, feeding on +1, and reload seating on a closed slide)

User feedback trend to be aware of (non-authoritative but useful)

Community discussions around the Kimber 2K11 line include a mix of positive high-round-count reports and some complaints around small ergonomic details (like safety “hot spots”) or finish wear. Treat these as signals to inspect and confirm fit/finish and comfort during your first few sessions—especially if you have a high-thumb grip. (reddit.com)

Conclusion

The Kimber 2K11 Eclipse 1911 Full-Size 9mm Optics Ready Pistol is a modern, optics-capable, full-size 1911-pattern 9mm built for shooters who want speed, capacity, and confident control in a single platform. Its 5-inch bull barrel and full-size geometry support fast, accurate shooting; its RMR-pattern optics readiness lets you build it into a serious dot gun; and the included 17/20-round magazines make it ready for real training volume.

For most buyers, the “make-or-break” decision point won’t be the base gun—it will be how you configure the optics plate and sights. Choose a proven plate solution, install it correctly, and you’ll get the kind of performance this platform is designed to deliver.
