FWIW; When I start reloading a new to me cartridge I start with the bullet originally used in the cartridge. In 9x19 I started with 124 gr TC FMJ. Worked great, so for the first thousand or so I used 124/125 gr. bullets, first 300 TC FMJ, then JHP. I normally don't notice recoi unless l'm thinking about it but I did notice a bit more with 147 gr bullets and slightly less with 115 gr., neither any great difference. I just got a 9mm 2" bbl revolver I'm expecting different recoil characteristics, but having perhaps 8-10 different 9mm bullets (115 JHP gr., 125 gr. cast/PCed, 124 gr. JHP and TC FMJ, 147 gr. cast nekkid and PCed, and some 147 gr. JHP on order.) I will experiment with all different weights/loads. My small Ruger LC9s has a bit more felt recoil than my full sized Masada, but neither are punishing, uncomfortable recoil..

(when I started reloading 44 Magnum I had a full blown case of "Magnumitis". I loaded most rounds hot and heavy, liked recoil and muzzle blast so 9x19 is no big deal for me).
