biggest drawback with the HP for me, was the crappy safety. Tiny lever, and no real solid engagement. For CCW use, that was not acceptable. Several times I found that the safety had slipped off. I no longer carry one.
I liked the idea of carrying a HP. But I had the same problem, I just didn't trust the safety, seemed to be too small and not a (like you said) solid engagement. Finally went down the road. Wish I still had it, I would have sent it off and changed somethings.
