Self defense shooting is NOT target shooting. If you're in a struggle, you'll be operating on adrenaline with maybe just seconds to act. Many CCW pistols have small crappy sights. Why? Because if someone is attacking you there is no time to look through the sights anyway. Ask a cop who's been involved in a shooting if they used the sights. If you really want to practice with a small CCW gun, try shooting 5 to 7 yds at a silhouette. Hold the pistol in front of your chest (not using sights or even a laser) and quickly empty the mag. If you have another mag empty that one, too. Then do it again left handed. Any shot that hits the silhouette is a good one.
