S&W M&P Shield 40 Magazine

Factory Shield 40 Magazine

This is the Smith & Wesson factory magazine for the M&P Shield pistol chambered in .40 S&W. It holds 6 rounds and comes from the same maker as the pistol, which is what most concealed carriers want in a spare or replacement magazine. The body is stainless steel with a polymer follower and baseplate, and numbered witness holes let you check the load at a glance.

Features

• 6-Round Capacity — The magazine holds six rounds of .40 S&W, the factory capacity for the flush-fit Shield 40 magazine.
• .40 S&W Caliber — The body is stamped "40 S&W" so it is easy to tell apart from 9mm Shield magazines in a range bag or drawer.
• Stainless Steel Body — The tube is stainless steel in a natural brushed finish, which resists rust from sweat and holster carry better than plain carbon steel.
• Numbered Witness Holes — Witness holes, small ports cut through the side of the tube, are marked 3 through 6 so you can see how many rounds are loaded without unloading.
• Polymer Follower — A polymer follower, the platform that sits under the cartridges, pushes each round up into position as the magazine empties.
• Steel Spring — A steel spring drives the follower and keeps steady pressure on the stack of rounds.
• Flush-Fit Polymer Baseplate — The black polymer baseplate sits close to the grip to keep the pistol short for concealment, and it comes off to give access to the spring and follower for cleaning.
• Factory Smith & Wesson Part — The magazine carries the S&W logo and is the manufacturer's own part, number 19933.

Fit And Construction

The magazine is designed for the Smith & Wesson M&P Shield in .40 S&W. It will not fit 9mm or .45 ACP Shield models, so check the caliber marked on your slide before ordering. The stainless tube, polymer follower and baseplate, and steel spring match the pistol's original issue magazine, so it handles the same as the one that came in the box.
