This factory new, extended 7-round magazine from Springfield Armory fits the XD-S 45.
It also includes 2 X-Tension sleeves to give you a flush fit with your gun.
The magazine fits in and stay without sleeve installed. If I install either of the sleeves the magazine wont stay in.
I love the extra extension the magazine gives to my XDs.
This magazine is a great addition to the XDS 45acp. It gives better grip and makes shooting the gun much more enjoyable. Good product at a fair price.
