Buidling upon my beginner handguns thread the other day I had a chance to go out and test a couple guns today. I got to shoot the Glock 22 and the M&P in 9mm. Feel and fit wise the M&P fit me much better. I don't have much handgun experience and right from the first pull I was fairly accurate with the M&P. I was not as accurate with the Glock from the same distances. I didn't feel the recoil from the .40 was over the top but it was definitly more than the 9mm, which made me enjoy the 9mm much more and I was able to snap off quicker and more accurate second and third shots with the 9mm. I'm not trying to start a 9 versus .40 argument. I enjoyed the 9mm more and I shot it better. I have not tried a .40 M&P but I wonder if it would be more accurate than the Glock which it probably would since the M&P fit me better but would the recoil be any different? I've done lots of reading and I see it said a lot that the modern 9mm shells are plenty potent. Can anyone point me to recommended home defense rounds in the 9mm just so I can do some more research? I appreciate all your help so far as I know many of you have much more experience than me and I'm glad you have been willing to share it.
