Hmm, how do solder that center pin if you can't pull it out of the connector? If it comes out of the connector easily, it's not a true captured pin connector (which is made for solid center conductor coax like LMR-400, LDF4, etc.), not RG-213, etc.

The one I have in my hand has a solder hole in it. I take it that there are
newer ones that have contacts that grip the coax center conductor?

Well here's the advantage of captivated center pins: the pin is NOT
bonded to the center conductor. IOW, if the coax center conductor
shrinks a bit, it can slide in the center pin and the pin stays put.

And that's exactly what you want it to do - especially with an N connector.
