Smith & Wesson Bodyguard +1 Magazine Extension

by editor

S & W Magazine Extension

The magazine extension is made to fit the S&W factory magazines for the Bodyguard .380. Enjoy a more controllable firearm- and one more life-saving round! Our testers reported they were able to improve their accuracy due to a better grip profile.



Push in the retaining button and remove the factory base plate while controlling the magazine spring. 

Clean the inside of the magazine body. Make sure the follower slides up and down without binding. (Some followers have a little bit of mold flashing that binds as the follower goes up and down). 

The +1 base plate is retained by the button plate and a “pinch” at the rear of the flange groove. 

In order for the factory button plate to fit properly inside of the extension, the small tab on the front end of the button plate must be sanded down or cut off with a razor blade. This will not affect the function of the button plate, and it will still work with the factory base plate. 

To install, hold the follower, spring, and button plate inside of the magazine body with your finger. Align the groove of the +1 extension with the flange of the magazine body, and push on. There will be a little bit of resistance as it should be a tight fit on the magazine body. 

Continue to push the button plate fully rearward. The button plate should seat with an audible snap. If the button plate is not seated in the hole of the +1 extension, you may need to tap the magazine or push the button plate with a small screwdriver or pin to allow it to seal fully. 

When properly installed with a +1 magazine extension, the magazine will now hold 7 rounds, while providing a more secure and comfortable grip.
