If you count them as obscure (I wouldn't, given that you can buy either for under $230 right now), I have carried a cz-82 and a makarov. The cz-82 is still a very, very viable carry option for me, for the sole reason that I shoot it very well. Every time I have carried it, I have always done so with the idea that a hit with a 9x18 is better than a miss with a 9mm, 40, or 45, and I still don't own a carry gun I can shoot as well (I'm getting there with my EMP, but am still not there yet)
Perhaps I just got a good one, but the trigger on mine is as good as a tuned 1911. In both DA/SA, it makes the DA/SA trigger of my Sig 226 feel like a gritty heavy pos.
