I have one of those as well as a P-40 which is the 40 S&W on the same frame.t They do have a bit of a snap to them and I found the magazine extension to be a good means of taming it a little as well as adding an additional round or two.
My manual states to not use bullet weights over 115 grs in the P-11 (165 gr in the P-40) as it can cause permanent damage to the frame. I also change out the recoil spring every 800-1000 rounds to help prevent wear. Check out www.ktog.org for additional information. I did the trigger smoothing modification and it helped quite a bit.
