Help: Springfield TRP Firing Pin Malfunction

[AR15barrels]

A 1911 firing pin can go super far without a bullet cartridge to stop it, Im not sure there's an actual problem here because it would never go that far normally when its fired. It's just probably getting wedged because it's going way too far.

This.

The gun has no problems in live fire.
Springfield will likely test fire it and return it with a note to the effect of "passed test fire, no problem found".

the firing pin stop should not drop free of the slide when the firing pin is not present.

Springfield will fix it and pay shipping both ways. Unless you think you can do a better job I would ship it to them.

True, but the hammer will hold it in place while the gun is cycling so even if its rattly loose, the gun still functions.
The firing pin stop will fall out of many USGI 1911's when the firing pin is removed if you degrease the parts.
It's normally the oil or powder fouling holding it in place.
Results of "bench testing" (other than headspace which is an actual safety concern) do not matter when a gun functions properly with live ammo.

Did you check the diameter of the firing pin itself? (If you installed the new one. Picture #1 the spring covers so can not see clearly). Might get caught because of manufacturer defect/tolerance or simply it's the wrong size pin. Maybe a few twists in extra-fine sandpaper to alleviate the stuck result. Or diameter is too small. Picture #4 shows the firing pin protruding quite a bit.
