This is surprisingly comfortable, and doesn't print unless you're wearing a tight shirt and bending over. I wouldn't advise doing the latter in the first place.
Lately it's been my Ruger LCP, but it shares time with my XD .40 sub compact. They are both reliable and comfortable to carry. Hoping to buy a Kimberly UC II soon to use as my main carry piece.
Keltec PF-9 with 115gr Speer Gold Dots, everyday everywhere I can legally carry it.
