Jack, the best bullet that I'm aware of is Beartooth's 200gr WFNGC. It will feed from a Glock - I shoot these in my G23 (.40 S&W). Finished off one wounded pig with it, seemed to work fine. Also one rattlesnake and another hunter used my Glock once to shoot a skunk that was invading his blind.
Try Blue Dot with this bullet.
If you can't get these in time, I'd just go with the heaviest Gold Dot hollowpoint that you can find (180 grain?).
A friend of mine has used Cor-Bon ammo in his 10mm Glock with good sucess. So that's one factory load that I could honestly recommend. I think they're on the web - do a search.
Best of luck.
