Yesterday morning, I fired my regular 100 rounds from my 3" CCW at 7 and 10 yards...because if I ever need to use it, most likely the situation will be 'up close and personal'. Afterward, though, I switched to a 1911 for 25 & 50. At the same time I was shooting, there were a couple of fairly proficient IDPA guys getting in some practice...and none of their targets were set beyond 20 yards.
FWIW, none of the states I'm familiar with which require live-fire qualification for CCW require applicants to shoot at over 10 yards. (When I fired my Illinois qualification, the guy next to me was shooting a SIG226 and barely managed to keep the absolute minimum number of rounds...21 out of 30...on his target; a full-size B27 silhouette at 5, 7, and 10 yards: 10 rounds at each distance.)
