I would think the g43 and hellcat would be simular to the sig 365 I carry. If you ever want to try owb with those 2. The Tucker deep carry 3 barely goes below the belt line.White Hat holsters. They are a well made holster that will last for a long time. You can get various prints on the kydex. They are based in Texas. Pass on the horse hide because it will take months just to break in.
Crossbreed Supertuck and Minituck. Hard to go wrong with this choice either.
I carry IWB almost every time. Over the years it's been mostly G19, G26, HK P30 SK, Kahr, G43 and Springfield Hellcat. The were other holster brand used, but those two were standouts in the IWB designs.
