Don't let the model moniker SP101 define its purpose. I didn't purchase this handgun as a defensive handgun, but rather as light weight field handgun. If a 4.2" GP100 can make a 50 yard shot at a deer, take out a snake at 5 feet, and then a rabbit at 25 yards, I can assure you that an SP101 with a 4.2" barrel is capable of the same.
You can see now, why I expect better. I would expect better, even if it were to be used as a self defense handgun.
