Got a new pistol and took this challenge with the first 20 shots ever. It's a CZ 75 Cold War Edition. Might be a stretch to say it will be a carry or home defense gun, but with 16+1 of 9mm (and 20 rounders available) I could do worse. Aced the challenge with about a 1 5/8" group. Didn't cheat either--I took all the first shots of a string double action.
