Springfield XDs won't extract round

[osok-308]

If your chamber is clear, you may want to do a "plunk" test with a few live cartridges before you reassemble your gun. It is also possible that this particular dummy round was manufactured out of spec.

Like this plunk test? It does look like the dummy round could have been out of spec.

I came here to post exactly this! I never knew to do this with my Kel-tec, but I wish that I had tried it while I still had it. With my Kel-tec, it would manually extract live rounds slightly easier than the snap caps, but it fired everything just fine. Honestly, it's probably just because it's a brand new gun and still pretty stiff.

This is the first time I've ever had this happen with a new pistol. Possibly because of the size and the strength of recoil spring? So I take it that I should probably only use dummy rounds after shooting it a bit first?
