I have one and only one .40S&W Pistol. It is a 4013 and I have it more for collection purposes then shooting. I want to have it as a back up for my 4516-1 which is my EDC. I bought some Federal Hydra-Shok 135gr ammo due to it being the only Hydra-Shok ammo around locally. Is this round to light and subject to over penetration? God forbid I ever have to use it but want to know if a heavy grain round is better. I use to have .40S&W before and the 180gr where a bit too much for recoil.

The lighter grain bullet should actually be less an overpenetration worry than a heavier one. As for recoil, you may find that 135 gr. a bit snappier than the 180 you remember. For any given caliber, heavier bullets tend to produce a bit less felt recoil than lighter bullets. Many compare the 180 gr. .40 S&W to the .45 ACP recoil-wise (feels more like a gentle push than a harsh snap) whereas 165 gr. and smaller feel more like a .357 SIG (or .357 Mag, for that matter), somewhat more punishing.
