It was a Smith & Wesson 642 Airweight in .38 Special. Made of alloy, it only weighs a pound. The barrel is less than 2 inches and the cylinder holds 5 rounds. Sights are very basic, with a blade in front and a groove in the top strap for rear sights. The grip is rubber and short enough to leave your pinky dangling unless you have tiny hands. It's also hammerless (well, the hammer is inaccessible). Everything about this gun is designed for concealed carry and close-range self-defense. Shooting targets with it didn't seem promising.
My initial impressions were kind of what I expected. I kept shooting high, and it took a bit to adjust to the long, double-action trigger. Recoil might be a bit much to a novice, but it was less than expected and not bothersome at all. I was firing Remington UMC 130gr. FMJs and could have shot all afternoon.
After about 10 rounds, I figured out the sight picture and trigger and began nailing targets. I wasn't getting tight groups or anything but hitting smaller targets at greater distances than this gun was really designed for. At 10 yards, I was able to hit a small spinner target (about 5 inches across) 3 times out of 5. For a "belly gun" (push it into the assailant's belly and pull the trigger), this was most impressive.
So, my gut instinct that snubbies are too much of a compromise to be worthwhile was wrong. The 642 is a great little gun. More accurate than it should be or needs to be, it's also completely reliable and a nice size and weight to be carried daily. The capacity is about half what one could get in many small autoloaders, but a 5-round speed strip for reloading wouldn't add much bulk.
One suggestion I would make is to consider the Crimson Trace laser grip. I didn't shoot with one, and it adds another $230 to this $400 gun, but it would also add about a half inch of grip for your pinky and compensate well for the minimal sights, particularly in low-light situations.
