I could wear a 30 waist but I buy 32 to accommodate my holster, Even with a double stack in my pants they are still a bit loose. Are the 32's that you wear now loose? If so then you could probably stick with 32's. Best way to tell is to stick the gun (after it's been safety checked) down your pants about where you will carry. If your pants feel loose stick with the same size. If they fit just right or snug you want to go up a size.
