What works for me may or may not be suitable for others. I carry IWB (inside waist band) on my kidney. My normal edc is a 9mm with 15+1. I have a few different makes and models. It doesn’t make a whole lot of difference to me except the sizes and weights are unique to each gun. I have a single stack 8 shot for tee shirt and shorts weather. I have a 10mm 1911 tricked out I’m tempted to carry, but so far it’s a range gun.
I really like the DeDantis pocket holster “the Nemesis” They are a soft plastic outer with a small pebble finish. They stick where you put them and they don’t have any belt loops. They work in a back pocket but I don’t keep it there unless it is a short walk. I have a similar model made by Remora for full size pistols. A leather 2″ gun belt to hold up my pants keeps the whole rig in place.
