I carry a variety of weapons depending on where I am going and what I feel like.
Sig-Sauer P239, IWB in a Galco seude holster with thumb break. Or else OWB in a Fobus Paddleback.
Springfield XD-9 4" Tactical, IWB in a DeSantis nylon holster, or OWB in a Springfield XDGear paddleback.
Glock 21 .45acp 1st gen, OWB, in a Glock belt holster.
I carry IWB's with a Tee shirt cover, strong side, 4 o'clock; OWB's, also strong side 4 o'clock, but tee shirt under, button up shirt or loose jacket cover.
Every now and then I Mexican carry something but that's usually just when I am out on my property.
The biggest part of "hiding" a CCW is choosing clothing that is not too baggy, not too tight, not too loose. I've lost some weight over the past year or so so now my pants are all one size too big- which is perfect for CCW. My problem when I first started CCW'ing was I liked to wear these triple XL baggy silk shirts thinking I needed to cover everything! Problem was they hung like a tent and tended to snag on the holster so they made it worse! Properly cut shirts make a medium pistol vanish assuming you are not "very heavy" then the bulges will cause funny things to happen; but the natural shape of the body lends itself to the clothing hanging just right so you don't even see the gun usually. The biggest thing to remember is that you have to NOT stand like there is something on your hip, don't keep feeling for it, don't keep self consciously tucking your shirt down, etc.
Sure you may print a little but most people today wouldn't notice an open carried weapon let alone a well concealed IWB. And if anyone sees the holster clip or belt loop they think it is a cell phone bracket.
The biggest problem I have is that I don't like having the rear sight dig into my abdomen when I sit in a vehicle with seat belt on
; by sliding the holster slightly or adjusting the rake I can make it so I do not even notice the gun while driving.
