For bear the Underwood hardcast recommended above would be a good choice provided it stabilizes from your barrel. I wouldn’t recommended anything heavier than 200g. Shoot 4 or 5 rounds into some cardboard and make sure that the holes are round. Glock barrels don’t do well with lead but hardcast helps and the coating should help. Check your barrel after a few rounds and clean the leading out if needed.
Midway usually has Underwood in stock. Underwood also makes a 180g bonded JHP @ 1300 fps. That should do the job as well.
