I wish I trusted automatics not to jam
Good quality pistols are trustworthy for the most part,.... Jams and malfunctions are a lot of times caused by user error such as " limp wristing" ( not a good grip or not strong enough), not practicing enough to get to know the weapon, ( types of ammo it runs good) or break it in properly, etc....
But that being said, unless you're a skilled shooter and practice often, a revolver is the best choice....esp. If you have to shoot off handed or one handed. Which may be the case in a defensive situation....( and should be part of your practice routine)..
