In theory, striker is more reliable because theres nothing that could interfere with it and really not much that could ever break. All it has is a coil spring around the firing pin. With hammer fire, the hammer strikes the firing pin. Theres more things that could go wrong, such as the hammer breaking, mud getting between the hammer and firing pin, etc.So you're saying that hammer fired handguns don't work as well?
Thats not to say that hammer fire is bad, but if you are going to split hairs on guns, well, there it is.
