When I had a 9 mm, I ran HST in it... however I agree with the previous posts that there are many other choices that reliably penetrate/expand and they might be easier to find (but they might not be as perfect as the HST).
If you can find HST, I definitely recommend that as your go to choice. My local shop recently had HST for approx $1 per round. Sold completely out in a handful of days. They also had a mountain of Gold Dots. Gone as well.
