The thing about a small single stack (or any gun for that matter) is it should be tailored made to the individual. I repeat "Tailored" to to the individual. When I wanted to make a change from my EDC of a Ruger LC9S, I took my time. I spent months shooting every thing out there. Club members allowing me to shoot their guns, rental guns ETC. Yes, it was a long process and time consuming and you could say expensive.(although I did enjoy shooting so many different guns). Grips, triggers, recoil factor, acquisition to target, reliability etc. have to all come into play for the Particular gun to be a precise fit for the individual. For me, it turned out to be the Beretta Nano and have come to appreciate it more with each shooting session.
A Glock, Kahr, Ruger, Springfield and on and on, all really nice guns. Just spend the time to find out what you want. Yes, take some recommendations, as a starting point, but you will have to shoot all of them within reason to make the final decision.Don't be taken in by ADS, Most Popular etc. Have fun on this journey. When you find the right gun, you will almost know it immediately. It will be totally reliable and it will be a totally enjoyable to shoot. It should be the firearm you shoot most frequently. JMHO
