Here would be my go to list. Kahr CW9 or CM9, Ruger LC9s or LC9s Pro or Smith Shield. The PF9 doesn't even enter the picture. The Springfield XDS was built as a 45acp and I think that is where it shines. The Walther CCP is larger but the PPS is a great pistol but the price may be to much. As is the Glock 43. I have owned all of these pistols and shot all of them but the CCP. You can get a very good trigger with the Shield and the 43, if you are looking that direction. Now with all this being said, my go to gun is the Glock 43.
