I was considering having Ian at Herron convert mine. Changed my mind when I thought about it for a while. I'm not going to hunt with it since I have better rifles for that and I don't need more firepower since the only thing I do with it is bang gongs and make holes in paper.
If your going to get one in 10mm I really hope you are a handloader, factory offerings for ammo are pretty weak, you need to load your own to really see the advantages of 10mm. Most factory loads are not much better than 40s&w.
Talk to your favorite retailer who sells Vectors and ask them to order you one.
