Ruger SR40 - 10-Round Magazine

SR40 10-Round Magazine

This is Ruger's own magazine for the SR40 pistol. It holds 10 rounds of .40 S&W and fits both the full-size SR40 and the compact SR40C. SR40 owners use it as a spare for range days and training, or to replace a worn or lost original. On the SR40C it sits lower than a flush magazine and extends past the bottom of the grip, which gives your little finger more to hold.

Features

• 10-Round Capacity — The magazine holds ten .40 S&W cartridges when fully loaded.
• Double-Stack Design — Rounds sit in two staggered columns that narrow to a single feed position at the top, so the magazine holds more without getting longer.
• Blued Steel Body — The tube is steel with a blued finish, a controlled oxidation treatment that darkens the metal and helps it resist rust.
• Numbered Witness Holes — Small viewing holes marked 4 through 10, split across both sides, show how many rounds are loaded without emptying the magazine.
• Polymer Follower — The follower is the plate the spring pushes up under the rounds, and here it is molded polymer so it moves smoothly inside the steel tube.
• Removable Floor Plate — The polymer base pad comes off so you can strip the spring and follower for cleaning.
• Factory Markings — The body is stamped with the Ruger logo and "SR40 40S&W" so it is easy to tell apart from other magazines in a range bag.
• Made In Italy — The tube is marked Made in Italy.

Fit And Construction

This magazine is Ruger part number 90351 and fits the SR40 and SR40C. It does not fit the 9mm SR9 or other Ruger models. The body is blued steel with stamped feed lips and a polymer base pad that seats under the grip. In the full-size SR40 it fits flush. In the shorter SR40C grip it extends past the magwell, the opening at the bottom of the grip where the magazine goes in.
