Key Features

• Original 1911 Frame with Type 1 Smooth Mainspring Housing — WHY IT MATTERS: This gives you the exact feel of a pre-1924 1911, with that classic arched backstrap that sits low in the hand for better recoil control.
• Period-Correct GI External Parts — WHY IT MATTERS: From the small thumb safety to the spur hammer and flat trigger, every external part matches the original A1 pattern, so your gun looks authentic at the range or in a display case.
• Checkered Walnut Grip Panels — WHY IT MATTERS: These double-diamond grips provide a secure hold even with sweaty hands, and they’re made from real walnut, not plastic, so they age beautifully.
• Colt Parts Compatible — WHY IT MATTERS: You can swap grips, sights, barrels, and most internal parts with standard GI-spec 1911 components, making upgrades or repairs easy and affordable.
• Lifetime Warranty — WHY IT MATTERS: Cimarron stands behind this pistol for as long as you own it, so if anything breaks due to materials or workmanship, they fix it free.

FAQ

Is the Cimarron A1 1911 compatible with standard 1911 holsters?

Yes, because it uses the original GI frame and slide dimensions, it fits most 5-inch 1911 holsters designed for the 1911A1 pattern, including leather and Kydex models.

Does this pistol have a firing pin safety?

No, it uses the original Series 70 design without a firing pin block. This gives you a crisper trigger pull and is preferred by many traditionalists, but means you should carry it with the hammer down on an empty chamber for maximum safety.

Can I upgrade the sights on this Cimarron A1?

Yes, the dovetail is cut to GI specs, so you can install aftermarket sights from brands like Dawson Precision or Novak. Just note that the front sight is staked in place and may require a gunsmith to replace.

What kind of accuracy can I expect from this pistol?

With quality .45 ACP ammunition, expect 3- to 4-inch groups at 25 yards from a rest. The barrel is button-rifled carbon steel, and the fit is tight enough for reliable combat accuracy.
