I agree with some of the others here that at SD ranges, with 9mm, the change in POI will be so small that it's irrelevant. In that scenario the more one practices and becomes familiar with their gun, the more natural and instinctive it will be to use under duress. The cheaper the ammo, the more one shoots. To a non-reloader, the difference in costs between defensive ammo and utility ammo can be great and can have a significant impact on how much one practices. To most handloaders this difference is small and sometimes isn't enough to justify shooting something different. Many times we just use the plinking stuff to save wear and tear on our guns and on us. That said, I advise you to still shoot enough of your defensive ammo to make sure it is as accurate as possible outta your gun.....and don't make a decision on your ammo because of what a friend or the media tells you is best. Try different types to see what performs best and shoots the most accurate outta your gun, then make the switch to cheap practice rounds.....and if your cheap practice rounds are more accurate than the SD ammo you have, you might want to consider using it for your SD. I see all the time where folks put more importance on the hype the manufacturer of a new bullet puts out there than how the round actually performs outta their weapon, and sometimes, because it is so cost prohibitive, they don't shoot enough of it to realized, it don't shoot worth a hoot outta their weapon.
