Rock Island 1911 40SW Magazine - 8 Round Blued

1911 .40 S&W Magazine

This is an 8-round replacement or spare magazine from Rock Island Armory for 1911 pistols chambered in .40 S&W. It is built for owners of the full-size Rock Island 1911 A1 who want extra magazines for range days, training or a carry rotation. It also suits shooters running a compatible 1911 clone in the same caliber. The steel body is blued, and a padded base pad sits at the bottom.

Features

• .40 S&W Caliber — The magazine is sized for .40 S&W cartridges and should not be loaded with other calibers.
• 8-Round Capacity — It holds eight rounds when fully loaded.
• Single-Stack Design — Cartridges sit in one straight column, the classic 1911 layout that keeps the grip slim.
• Steel Construction — The body, feed lips, follower and spring are all steel, and the body is heat treated for durability.
• Blued Finish — Bluing is a chemical treatment that darkens the steel to a deep black and gives it some resistance to rust.
• Witness Holes — A row of holes along each side lets you check how many rounds are loaded at a glance.
• Padded Base Pad — A black pad on the floorplate gives your palm more to push against during a reload and cushions the magazine when it drops on hard ground.
• Exposed Steel Follower — The follower, the plate that rides on top of the spring and pushes rounds up, is steel and shows at the top of the tube.

Fit and Construction

Rock Island Armory, the 1911 brand of Armscor Precision, designed this magazine for its own full-size 1911 A1 pistols in .40 S&W. It also fits compatible 1911 clones in the same caliber. A cutout on the side of the tube engages the pistol's magazine catch in the standard 1911 position. All-steel construction keeps it close to the original 1911 pattern, so it suits shooters who prefer metal magazines over polymer.
