Springfield XDs in a Mika pocket holster. .45 or 9mm same size.
9mm with 7 rd. magazine works in my pocket. 9rd. magazine, 9mm,does not work in my pocket, but works well as the spare. My experience is that butt size or length determines pocket carry. BTW, 6'-5",280#, and jeans 98% of the time
Carried a .38, charter arms, police bulldog, in my pocket, my years in NOLA, especially while in the projects. There wished it was BHP, but the police guys with or near us said it had to be pocket carry, and to make sure we could run fast, but still be able to change directions!
