That is correct Don; they do require fine adjustment to work properly due to the design; even a slight difference in magazine dimensions will cause the safety to not release the trigger.

I'm not sure this is "other confirmation" you are looking for; but, as they used to say in math class- "the solution is obvious", or in this case the reason, IMHO.
