I got my dad the EZ .380 before there was such a thing as the EZ9. He is 82 years old and can no longer rack any of his semi autos. In fact he gave me all his 1911s because he can't rack them or comfortably shoot them anymore. He can rack the EZ .380 pretty easily and the problems that were so prevalent in this gun when they first came out, (which is when I bought his) his hasn't exhibited any problems and we have over 1000 rounds through it now. Neither him or I were ever fans of even the 9mm, much less the .380. We both have always shot and owned .45s. I still very much prefer them. He shoots the .380 pretty well and keeps it loaded with quality SD rounds. Sadly I think his mental faculties have largely rendered him incapable of truly defending himself should the need arise. He still keeps the EZ close to him for comfort, but I have given my mother, also a fine shooter for many, many years, a nice revolver ( Colt Diamondback .38 sp ) and since she always favored the old Maks she has my Russian 9x18 Makarov. She also knows her way around the BPS which she has handy.
Dad mentioned upgrading to the EZ9 a few months back, but between his physical and mental condition and the fact that a 9mm isn't going to gain him any advantage at the kind of distances he would encounter I gently nudged him away from the idea.
