Now to answer your question, Fiocchi primers are great primers, I've shot 15k. Have no experience with Ginsex but I have friends who use them, overall tbey work fine as long as you don't have any fancy trigger system in any type of striker fire pistol. Servicios are harder then normal primers and a little harder to load based on my experience. I did get a light primer strike on a recent batch of 300 rounds I shot, that was on a 2011 pistol.
