Well, not on mine.  However, I worked on a few with Wobbly loading gates.  Usually the result of a miss-sized screw.  I nuisance but not difficult to fix.  It is important the loading gate NOT stand proud of the recoil shield.  If it wobbles above the recoil shield, it may need the edge to be slightly broken or lightly beveled so the rotating cartridge can shove it out of the way.

My screw is tight. But still has wobble. Like a 2mm worth of wobble. Is it slight? Yes. Annoying? Yes.

Here is the uberti open top parts list from Taylor's
https://taylorsfirearms.com/catalog/product/view/id/3381/s/uberti-open-top-revolver-parts/category/301/

we can see that the loading gate is held on by screw # 675, a shoulder screw,
and is held closed by the external spring #136 and screw #145

If the gate is wobbly, without having the revovler in hand, my guess would be along the lines
of Coffinmakers post: that is, the shoulder screw is most likely undersized.

One solution would be to bush it out, but the easiest would be to get a shoulder screw
sized correctly to the hole in the loading gate.   

hope this helps

 :)  And Another Thing   ;)

If the screw is Tight (DO NOT over tighten the thing please) and you still have wobble, the first step is to order a NEW screw.  Have some Coffee while you wait.  Choke over the fact that the postage is three times the cost of the screw.  Have some more Coffee.  I recommend "Sumatra".

With new screw in hand, remove the OEM screw and the loading gate.  Put the screw back in it's hole.  Get out your Sherlock (Magnifying Glass).  Under strong light, see if the screw is actually bottoming out the Shoulder.  If not, remove some of the threaded portion of the screw until the shoulder buttons out.  Then put it all back together with a drop of BLUE LocTite.  Should you really bugger it up, you have your Brandy Knew-Two-U replacement screw in hand.  Burma Shave

Nobody has mentioned it yet, but a weak spring could also cause a wobbly gate.

Mine also, must be a common problem.

I did what Coffinmaker suggested and that improved it a little. What I discovered was, when loaded, the cartridges seem to hold the gate in place.
