Description
If you're running a compact XD-M in .45 ACP and want more rounds on board without sacrificing what makes the gun so portable, this is the upgrade your range sessions and backup loadouts have been waiting for. Springfield built this magazine to OEM specifications with a stainless steel body that won't quit, paired with a steel spring and polymer follower for reliable feeding shot after shot. The polymer base plate keeps things lightweight while still being tough as nails.
What Sets the XD-M Compact Extended Magazine Apart
This isn't some aftermarket experiment. It's a factory Springfield magazine engineered to convert your compact platform into something that handles like a full-size grip when you slide the included X-Tension sleeve over it. The sleeve fills the gap between the magazine base and your grip frame, creating that seamless transition from compact carry to extended handling. You get all 13 rounds, and your hand finally has somewhere comfortable to live on the gun. People who own these consistently mention that the extra capacity doesn't feel heavy or clumsy even after a long day of use.
Built for the Compact Shooter
The magazines are straightforward to load and perform flawlessly with any .45 ACP ammunition you run through them. The steel wire spring design ensures feeding stays smooth whether you're at the range or depending on the gun for something more serious. Everything locks in tight with the secure mag well fit that XD-M owners have come to expect from factory products. The witness holes on the side let you count your rounds at a glance without removing the magazine.
Pairing with Your Backstrap
This specific model (XD45451) pairs with Backstrap #1. If you're running a different backstrap size, Springfield makes versions for #2 and #3 as well, so you can match whatever grip configuration works best for your hands. Both the original XD-M and the newer XD-M Elite compact models will accept this magazine.
