Its a Kimber solo Carry. Bought it used for cheap. I didn't run into any malfunctions like some mentioned online even after shooting lower grain rounds than they recommend though I only have about 100 rounds through it. Its not my favorite and not one I carry. Racking on a full mag is harder...
Waited tirelessly for Magpul's FDP/FDC but came off the range at Tim's and saw the guys playing with this. Couldn't leave without it! B&T BWC. It has since been built but I don't have pics.

I get custom ones made for racing. Dawn at EarEverything is here in Indianapolis does great work and will come to you to make the impressions. And when you lose one she keeps the molds on file.

Can't wait to get one. I've been on the hunt for one of these for a while. No one seems to have any in stock. Currently have the LCP MAX as my occasional micro carry
