Optimus Defense +1 Magazine Extension for XDs-45 adds one more round of ammo and a pinky finger grip to a standard size (5rd) XDs-45 magazine. With this extension, your XDs magazine will hold 6 rounds of 45ACP. Designed for concealed carry, this magazine extension is rounded and as small as possible so to not "print" any more than the factory configuration.
To install, simply remove the factory XDs magazine base plate and slide on the Optimus Defense +1 Magazine Extension. Warning: compressed magazine spring could shoot out, so wear safety glasses when removing and installing magazine bases.
Save 20% by ordering a 3 or more.
Note: This extension is not compatible with the XDs 45ACP 7rd magazine.
* This 45ACP +1 Extension will also fit and function on XDs-9mm 7 and 9 round factory magazines, but removal of this 45ACP extension on a XDs-9mm magazine can be very difficult . If you have L-XL size hands, you might prefer this 45ACP extension on your XDs-9mm. For the 9mm version (OD022), click here.
