I prefer metal hammer fired guns, but have my fair share of polymer striker fired guns from Springfield Armory, Glock, Sig, S&W and CZ. Of all of them, I prefer the CZ and the Sig 320. It has to do with how they fit my hands, my Shooting style and how quickly I can shoot them accurately.
In all honesty, think any of the polymer striker guns I mentioned can serve you well, you just need to find the one that fits you and your needs best.
Nice to have options
