Most of the data I have seen for 9mm reloading is based on a 4 inch barrel. My XD-9 has a 5 inch barrel. Does this even matter? Do I have to adjust powder loads at all?
Barrel length difference of one inch will give you a slight velocity edge and a longer sighting radius. However, the length of the barrel means nothing in regard to pressure generated by the same loads. Use that data with confidence to work up (for accuracy), your loads. If they are safe in a four-inch, they are safe in a five-inch.
Sometimes you get what you pay for, sometimes you only pay more for what you get.
