Wt Mag-140-Dlc Mag 9Mm 20R Dbl Stk 1911 Dlc/Ss

The Watchtower Firearms MAG-140-DLC is a high-capacity 1911 magazine engineered for shooters who want more rounds between reloads without sacrificing the classic 1911 platform. This 20-round double-stack magazine feeds 9mm Luger ammunition and pairs the durability of stainless steel with a DLC (Diamond-Like Carbon) finish—a hard, slick coating that resists corrosion and wear while reducing friction for smooth feeding and extraction. Whether you're running a modern 9mm 1911 at the range, in competition, or for duty use, this mag delivers reliable capacity in a proven design.

The double-stack geometry allows the magazine to hold significantly more rounds than single-stack alternatives while remaining reasonably compact for a 1911. The DLC/stainless steel construction means the mag won't rust or stain easily, even if you're training hard or carrying in variable conditions. It's built to the standard 1911 magazine profile, so it locks into standard 1911 magwells without modification.

Watchtower Firearms magazines are purpose-built for practical shooters: reliable feeding, consistent springs, and finishes that stand up to regular use. If you shoot a 9mm 1911 and want the flexibility of carrying more ammunition, this mag is a straightforward upgrade that doesn't require gunsmithing or compatibility guesswork.

Frequently Asked Questions

Will this 20-round 9mm 1911 magazine fit my standard 1911 magwell?

Yes. The MAG-140-DLC is designed to standard 1911 magazine dimensions and will lock into any standard 1911 magwell without modification.

What's the difference between this magazine and a single-stack 1911 mag?

The double-stack design allows this magazine to hold 20 rounds instead of the typical 7–8 rounds in a single-stack 1911 magazine, while staying reasonably compact. The trade-off is slightly more width, but it's still manageable in most modern 1911 frames.

Why does the DLC finish matter?

DLC (Diamond-Like Carbon) is a hard, slick coating that resists corrosion and wear better than bare steel or bluing. It also reduces friction, which promotes smoother feeding and extraction over time and in harsh conditions.

Is this magazine good for competition or duty carry?

The 20-round capacity and reliable design make it suitable for range training, competition, or duty use where higher capacity is an advantage. As with any magazine, test it in your specific firearm before relying on it in critical situations.
