I have NEVER assumed any .22 pistol would be as reliable as a center-fire gun. It's just the nature of the beast. If people are going in to this thinking that the G44 will be 99% reliable, they need some expectation management.
The question should not be: "Will this gun be as reliable as my G19?"
The question SHOULD be: "Will this gun be as or more reliable than a Ruger Mk4? Browning Buckmark? Sig or S&W .22 duty clones?"
