Description
The Kimber Stainless LW Arctic 45 ACP is a 5 inch Government-size 1911 that pairs a silver aluminum frame with a stainless slide, black and gray laminate grips and a red fiber optic front sight.

Kimber Stainless LW Arctic 45 ACP Overview
The Arctic (model 3700593) is a lightweight take on the full-size 1911. Our store title listed 5.25 inches; Kimber lists a 5 inch stainless match-grade barrel with a black match bushing, and 5.25 inches is the pistol’s height. The aluminum frame trims weight to around 31 ounces, and the stainless slide has front serrations, a white-dot rear sight and a red fiber optic front. The 3-hole aluminum trigger is set around 4 to 5 pounds, and one 8-round magazine comes with the pistol.
Lightweight Frame
An aluminum frame cuts several ounces from a steel Government model, which helps if you carry a 5 inch 1911 on your belt all day. The trade-off is a bit more felt recoil with 45 ACP, and aluminum frames have a shorter service life than steel under a very heavy round count; most owners never come close to that limit.

Sights for Fast Shooting
The red fiber optic front glows in daylight and pairs with a white-dot rear for quick sight pickup. Fiber optics do not glow in the dark, so add a weapon light or plan a sight change if low-light use is a priority.
All-Silver Look
The silver frame and stainless slide give the Arctic a bright, uniform finish that resists corrosion and makes the pistol easy to see in a case or safe. Contrasting black and gray laminate grips with smooth and checkered sections give a sure hold.
Trigger and Accuracy
The match-grade barrel and bushing and a light aluminum trigger give the accuracy people expect from Kimber. A 5 inch slide gives a long sight radius, making this a good choice for bullseye practice or steel matches as well as carry.
Honest Trade-Offs
Eight rounds is modest compared with double-stack pistols, and only one magazine ships with the gun. A bright silver finish is less discreet for concealed carry. Aluminum frames should not be used with very heavy +P loads for long periods; standard 45 ACP is the best diet.
Cleaning and Care
Clean the barrel and breech face after shooting, keep the slide rails and barrel hood lightly oiled, and wipe the silver finish to remove fingerprints. Inspect the recoil spring, slide stop and bushing at each cleaning. Check the fiber optic rod for cracks; replacement rods are inexpensive. A well-cared-for lightweight 1911 should give many years of service.
State Laws and Ownership
Eight-round magazines are legal almost everywhere, but handgun-roster states may not list this model, and permit and carry rules differ by state. Check your state and local rules before ordering, and ask your receiving FFL if you are unsure.

Before You Buy

Plan on spare magazines, a holster for a 5 inch 1911 and 45 ACP practice ammunition. Keep the recoil spring fresh to protect the aluminum frame.
