Very comfortable.
Very comfortable rig. I prefer to shoulder my ppk/s because it's a few ounces heavier than my other (polymer) edc weapon. This setup works best with a collared shirt IMHO because the strap rubs the back of my neck when wearing a t or sweater. I have other shoulder rigs that are padded and comfortable but this one is much less noticeable while wearing a blazer or windbreaker. The holster itself is very well made, fits my ppk/s perfectly. The thumb break works w/o flaw enabling me to focus on the task at hand with no worries.
