He has said he supports self-defense. I'll see if I can find some documentation.
Found this:
Dalai Lama: Individual case? For example, if mad dog coming, almost certain now bite you. Then if you say, non-violence, non-violence and compassion&
Hana Gartner: You get bitten!
Dalai Lama: That's kind of foolish! You have to take use of self-defence. But without harming, without serious harming another, I think that's the way I feel. If someone try to shoot on you, then there is no possibility to run away, then you have to hit back. Then possibly not on head, but leg or something like that. So that's not serious hit back, but more lenient way, more gentle way.

According to the Dalai Lama, If someone has a gun and is trying to kill you, it would be reasonable to shoot back with your own gun.262
