You do not want to have a gun that you’re not comfortable with. Having to deal with a high stress situation and then trying to use a gun when you don’t have brain-dead levels of familiarity with it is asking the trouble. Luckily it’s fairly cheap to build most of the muscle-memory with dry-fire and handling drills. But if you plan on using it for home defense or personal protection, you need to be prepared so that your mind can focus on other things during your troubles.
