I am breaking in a 9mm Shield. The range I'm using has fixed firing line and target frames, 25 yards only, offhand two hand hold, slow fire. Longer distance than self defense. I get tired after 50 rounds or so... lose my focus somewhat. First trip with the Shield got about ten rounds in the bullseye, the rest all over target. I'm at 250 rounds and now it's 50% in the bullseye, the rest close. By the end of break in I should be around 75% in the bullseye. The Shield is more accurate than most of us can hold it. There's folks that say I'm nuts for shooting a ccwbpistol at bullseye distances but guess what, confidence is a big part of handgun shooting and when you can confidently make hits at 25 yards the 7-10 yard stuff is real easy. Find target, look at front sight, press trigger, with both eyes open.....Mike
