I've got a Kimber conversion and it's a hoot (especially with Stingers). It doesn't like lead round nose too much, but if it's plated it'll feed it no problem.
I'm still trying to get a decent group out of it for bullseye though. The likely problem is my ammo choice, my stock Norinco trigger and the fact I rarely practice with my handguns. I'm still a threat in our rimfire pin shoot at the club though.
