Unless you're in the boonies of AZ and some nefarious drug/human smugglers decide they don't want a witness. What if you have to, God forbid, engage someone with a rifle or shotgun? Or even another handgun? Also, the discipline for shooting 25 yards is different from 7 yards. At 7 yards I get a "good enough" front sight picture and yank the trigger, at 25 I focus closely and pull the trigger smoothly so as not to upset the perfect sight picture, amd at 3 yards I instinctively point the muzzle and mash the trigger. It doesn't hurt to calibtate your mind and muscles to perform appropriately for the situation. Also, long range shooting exposes issues that aren't as noticable at 3-7 yards.
What if the enemy combatant is using cover or only partially exposed? I try to prepare for more than the obvious and commonly assumed frontal close range assault.
My EDC is a Glock 27. It's my ankle gun on duty. As accurate as my Glock 22, but at the 25 yard line I need an extra second to make hits with it. I know when rushed I throw rounds low/right, and on a "bad day", I'll use Kentucky windage by aiming 6" up/left on my qual target to ensure I hit the scoring area. I'm a southpaw.
