re: what's your cc holster for glock 19

Appendix carry is definitely the easiest way to carry a full size gun and keep it concealed. I like my ravenconcealment eidolon, other like the Haley strategic incog, a good cheaper option to see if you like it is phlster skeleton gen2 with a wing attached, Trex arms sidecar. Probably lots of other good ones I am forgetting.

For behind the hip generally people go with a hybrid holster like a crossbreed or something like that. No my favorite but just my opinion.
