Springfield, we have a problem…

On most modern auto pistols, the back side of the slide lock has a tab (lug) that projects in to the cutout area in the mag body. Once the last round is fed from the mag, the follower will engage the slide lock’s tab and put upward spring pressure on it.

Just about all modern auto pistols work this way to lock the slide to the rear once the last round is fired.

You can see the triangular slide lock being pushed up by the plate on the mag follower of my Springfield XDS here:

On most handguns, including the Springfield XD and XDM, the slide lock protrudes in to the mag far enough so there is no chance of the mag follower failing to engage it once empty.

With the XDS, the triangular protrusion barely catches the edge of the metal plate that it is supposed to catch on the mag follower.  A little but of sideways pressure or a slightly off-center and push from the mag spring, and fail…

The slightest off-center engagement causes the slide stop to miss and the mag follower to push up past the stop’s tab.

Once the last fired casing is ejected, the slide either closes on an empty chamber unrestrained by the slide stop or hangs up on the back of the follower. As seen below:

With all of the recoil spring’s pressure on the back of mag follower, the slide catches but is not locked open.

When the mag is dropped, the slide closes on an empty chamber.

I’ll be calling Springfield on Monday.  I have five mags and this is repeatable on all of them.  Two x 5-round mags came with the gun and I bought three more 7-round extended mags.

Back in the 90’s I had a problem with a Springfield 1911.  I sent it in and received back a masterpiece of reliability and accuracy.  This is what made me a long time customer of Springfield Armory.  If they stand behind the XDS and fix it the way that they stood behind and fixed their 1911 nearly 20 years ago, I’ll be one very happy camper.

Stay tuned!

    I sent my xds back on Monday for this exact reason. Let me know how long it takes to get yours back. Thanks

    I just picked up an XDS as well, but have not had a chance to fire it yet. I will be doing so shortly. Before I came across any of these discussions, I tried using some snap caps. I felt like the way the slide release was behaving was not quite right (at least in comparison to my XDM 45). Since then I have seen this issue reported by many, so I have a feeling I will be experiencing it as well. Hopefully not though.

    Great pics explaining the exact problem, some pics from other people in the forums were dark and blurry. This is the first time I finally understood the issue. I am also curious how long it takes to get your piece back from SA, so please keep us posted.
