Recently bought two GX4's, same day. Serial numbers are 15 apart, XXX71, and XXX86. I have a problem with locking the slide back on one without an empty mag in it (a different post in this forum), so while researching problem, I pulled the frame of the grip, to check the slide catch and spring. I noticed the upper rear support pin (4.12) was missing. Thinking I had dropped it, I looked for over half a hour. My workstation is such, it would be VERY difficult to lose something, but Murphy's Law...
Anyway, decided to take other one apart, to measure pin, and check my huge assortment of "can't throw THAT away!"s, in case I had one. So, was paying VERY close attention when I pulled it apart.
Gun Two is missing the same pin! Can't be coincidence. So called Taurus. Of course, the $1.00 pin is restricted! So, now both have to go back, to be" repaired ".
Both guns have around 150 rounds through them, no other problems, fired just fine. I don't know if the sear block rocking due to lack of support could do hidden damage.
This video shows how to look and see if your GX4 had the same problem. Just remove the slide, and try to rock the block. If missing, I'd call Taurus, or at least put in an appropriate pin. I DID ask the tech to pass the word up the chain of command, and she seemed concerned enough, I think it will get done.
When I get either one back, I'll do a teardown, and get a very accurate measurement of the pin, and update here.

Here's the video link, if I do this right...
