Is the extra bulk from extra mag on appendix holsters noticeable?

I'm turning 21 in less than a week and will apply for ccw permit asap. I am also trying to take advantage of the black friday sale.Is the extra bulk from extra mag on appendix holsters noticeable? For me comfort is first but if the extra mag doesn't add much bulk I wouldn't mind it via /r/CCW https://ift.tt/2OVBz4g
