I remember that I started off with 4 o'clock carry.
Then about 10 years ago, I had a job where I was constantly bending over to pick up boxes, wrap pallets, stock inventory, etc. So I needed a more concealed way of carry where I wouldn't be giving myself away.
I moved my P226, 220, 229, 228 to appendix in a Don Hume (at the time, leather was it) holster. Then when I'd leave work, I'd switch back over to 4 o'clock. Until one day, I stopped switching over and just left it that way.
I liked always having my weapon directly in front of me.
Afterwards when I worked at gun shops, ranges, training centers, and private security work, I'd carry 3 o'clock OWB and one spare gun appendix.
Now, as of about 5 months ago, I landed my first office desk job. 10 years later and appendix has stuck to me. I exclusively use
T5 Custom Kydex and their "HitchHiker" for all my concealed carry needs.
Ranging from the P229, P226, P30L, Glock 19, and so on.
My attire is a button down and tactical slacks that don't look tactical. Dress shows and incognito Vertx EDC Ready bag which I put my snacks, medical equipment, hygienic items and many more things in. I make sure they see me taking out stuff like my tooth brush, a protein shake packet, a tuna snack, etc.
In the "tactical" pouch I have 3 spare mags, a fixed blade, a multi-tool, and many others.
Appendix also lets me wear my backpack comfortable around town without hindering my draw in any way, shape, or form.
