I bought a PSA Dagger a few weeks ago, then bought another PSA dagger slide recently.

Took the new slide to the range today and round got hung up on way into chamber.  Initially thought it was the new barrel in the new slide.  Then thought maybe it's the recoil assembly.

Bottom line is after changing things out to narrow it down the culprit is the new slide.

Any ideas on how to make it work or just send it back to PSA for a replacement?

Mine was sticky at first.  Try cycling it a few dozen times.

Polish and buff the sharp edges
You may find some "extra" swarf that needs to be removed

I should have tried that.  I sent it back to PSA and they got it running and sent it back to me.  Maybe that is what they did.
