Apex Gun Parts lists the length of the UC-9 firing pin at 2.75" however I have heard of UC-9 firing pins sometimes being too long and puncturing primers. In any case, I'd take the bolt and striker assembly out of the gun and see how far the firing pin protrudes from the bolt face to visually check if there is an issue.

I measured the one for a Vector and it is 2.75".
The firing pin should protrude .045 from the bolt face. |

I believe Vector Arms is back in business- sort of. One of the original owners apparently bought out the remaining inventory, whole thing sounded like a shitshow….. Anyhow, I have been seeing him post up various parts on Gunbroker, can’t recall his user name there, but if you search for Vector UZI parts I bet you can find him. Know there have been some semi auto firing pin parts available.

It will depend on the direction the roll pin hole was drilled. It shouldn't matter.

Thank you gentlemen. I have been trying to figure out why the firing pin rear has a flat milled surface on half of it.

It's to clear the firing pin safety block. It was a feature on the IMI model B carbine. Here is a screenshot from Uzitalk explaining the feature. I think Century converted full auto bolts to semi and am not sure if this feature was on them.
