It could be just a matter of feeling. Like I could say to myself "I don't really feel like carrying my 5 shot .38 special but then I don't want to deal with my XD .40 with a full mag on a hot day either. So I will just split the difference and carry my XD with 5 shots in the magazine." Maybe even put 5 in an extra magazine in another pocket. I'm pretty sure my XD even with 5 rounds is still heavier than my .38 snub but the XD is slimmer.
