I like my PM9 a lot, but, if I can move to a 40, mo betta. But I don't know if the polygonal rifling makes much diff between the PM and CW as far as accuracy, and of the recoil please. I just bought a Taurus 740 Slim that kicks pretty good. If you can compare the CW40 recoil to other guns we may have one in common that I can equate to. Thanks!
