Short barrel Gold Dot, well proven. Save the duty barrel loads for duty length barrels, especially the 147 version. The 43 loses too much velocity in comparison to a duty barrel.
I have completely converted to AIWB with the 43, which I resisted for quite some time, so I do understand the dislike some express. Regardless the technique, my advice would be to avoid any holster, which has bulk in comparison to the size of the 43. There are quite a number of trim designs, especially appendix, that are first class, that work well with the 43.
