I would trust my life to .22 magnum. More specifically federal punch ammunition. There are two main concerns with rimfire reliability, duds and ejection issues. Duds are unavoidable and are baked into the cake at the ammunition factory. If you can accept that, then the question becomes do you go for a revolver or semi automatic. From what I hear, Rugar mkIVs have excellent ejection reliability so if you have the cash, you can’t go wrong there. Revolvers are also great and pretty cheap nowadays. Just pick what you shoot well with.
