I've been carrying either a Springfield XD9SC or Glock 36 with a IWB holster for the last two years. If your current pants have even a little bit of room in the waist then you should be fine. I haven't had to go up in size to be comfortable carrying all day. Be sure and use a belt designed for carrying to help distribute the weight and keep from making your pants sag on your carry side and you will be fine. I carry in the 3:30 to 4:30 position just fine.IWB ? pants size?
do you have to get a larger size of pants when wearing a IWB holster?
waist size I mean.
