Atlas Gunworks 9mm Classic Magazine, 20 Round, Stainless Steel (140mm)

This 140mm magazine fits 1911 double-stack handguns

The Atlas Gunworks Classic 1911 Double Stack Magazines are available in 17 and 20-round configurations. We recommend classic magazines to shooters looking for a tough magazine that feeds awesome and locks back reliably in most modular 1911 double stack and 2011 style pistols, including Staccato* and Springfield Prodigy. Gen2 classic basepads and retention plates make it easier to remove the basepad for cleaning, but they are incompatible with Gen1 setups. Please note the image to determine which generation you have.

• Caliber: 9mm
• Capacity: 20 rounds
• Tube: 140mm Stainless Steel
• Follower: Lockback
• Spring: + 18%
• Basepad Gen2: Aluminum, prevents over-insertion
