I have used Reington 1 1/2 primers for 9mm. They work just like the Winchester primers Federal primers and CCI primers I have used in 9mm. They all go bang when I pull the trigger.
Persoanlly I have found no differeance between any manufactures primers (as far as performance goes) I have worked up loads when switching between brands, but the load stays the same in the end. (at least for my pistols.... YMMV)
I would say they are all "safe" to use.
CHeers!
