My KAHR CM9 conceals well in a DeSantis Nemisis, but it's a bit tight for a reliable draw from jeans pocket. Cargo pants pockets being a bit looser work fine.
When wearing jeans I carry my CM9 in a Theis hybrid IWB holster similar to a Crossbreed. About the only thing I feel allows for a smooth draw from jeans pockets is my Elsie Pea, again in a Nemisis pocket holster.
