Hurst shifter linkage binding?
Just throwing this one out there....Has anyone had trouble with their Hurst shifter binding and not going into gear?
The shifter has been on the car for about 6 years now and the "binding" seems to be getting worse. At first I was convinced the clutch hydraulic system was not functioning properly, but have since replaced the master and slave with rebuilt units from Power Torque systems. Also i'm absolutely sure there is no air in the lines.
It doesn't happen all the time but usually is a first/second gear problem, either from a stop or slow creep. A quick shift to third and then back to first or second usually solves the problem.

Look for all the normal worn things, egg shaped linkage points and if they are OK I would open the side cover look at the shift forks and check the side cover shafts / gear lock out for to much wear

Wondering if anyone has encountered this with their short throw shifter...

How many miles on this car? It's certainly possible you've got synchronizer issues internally with the transmission. Has the transmission been "used" by you or a PO with maybe disregard for internals. Power-shifting etc? I'd think the likelihood of "internal/synchronizer " issues more suspect than the shifter parts but it's only a time thing so inspect away. Shift-rails and detents on the rails I don't believe are generally suspect.

How long since the trans fluid was changed? I had a mildly stiff 3rd gear on mine when I bought it. Changed the fluid out with Amsoil MTF. After a couple hundred miles with the new fluid it was shifting smoothly.

OP I'm quite sure is talking about a ZF shifter so he's "no side cover" to remove and he ain't got "egg shaped" linkage points.
I'd say this hints maybe 1 - 2 synchronizer issues.

A good thought. It's been 5 or so years since I've changed it with factory GM oil but could prob use a redo.

I also exchanged some emails with ZFDoc and he seemed to think it could be the 1-4 skip shift pin interfering. Even though the car has the override he suggested getting rid of it.

Just to make sure, check to see if the CAGS is the problem.
When you state: "It doesn't happen all the time but usually is a first/second gear problem, either from a stop or slow creep. A quick shift to third and then back to first or second usually solves the problem." those are exactly the conditions that will cause the CAGS to prevent it going into second. If you go into third, CAGS will not prohibit second gear.
If CAGS has been disabled then it is probably as others suggested. If it is the CAGS, you can disable it easily and cheaply to allow normal shifting all the time.
Good luck.
