I have tried some Syntech 9mm defense rounds in my Shield and P365 they work great. I have some retro .38spl Nyclads that I covet and will not shoot 125 gr HP 158 gr +P SWCHP and best of all S&W Nyclad 158 SWC +P The Syntech is just a modern version. The Nyclad as we all know are no longer available so they are as easy to find as a unicorn.
