    It REALY depends on the bullet performance such as expansion, barrier performance, & penetration.

    You need to do some research on the bullet type-- but from my research the 165gr .40 bullets have about the best performance for the bark & kick.

    I also carry a G-27 most of the colder weather months & I carry a 165gn.

    To me personally-- most quality bullets in any of the weights you mention will get the job done. With the G-27 (for me anyway) it's more about finding a round that has less muzzle flash at night from the short barrel G-27.

    Whatever you choose be sure to fire a few at night-- some rounds will flat out blind you on the first shot & THAT leaves you at a big disadvantage.

    I'd go with 180 grain. And that would be the Federal 180 grain HST. 180 generally gives the best penetration for a given level of expansion. Also, a 180 hitting bone will have more momentum to break through the bone. Then again, the difference betweeen 180 and 165 is not going to be huge.

    Not a 40cal fan at all but of all the bullet weights I've shot in the few I have owned I think the 180gr tends to have less muzzle flip so that'd be my suggestion.

    We are issued 180 gr Winchester Rangers. Pretty low flash. I've carried 165 gold dots off duty but I like the Rangers the best. I'm not a fan of the 40, being a 9mm guy, but if i had to choose, I'd go with 180 grain

    I recently looked into this for myself. I currently use Win 165 grain but bought HST 180 due to bullet testing I found on the net. I know that the lighter bullets (155 and below) are harsher on guns. Friend who works in the industry told me that when they break a 40 cal gun for testing purposes they use 155 grain to make it faster.

    I work for the 8th largest department in the country and have some crazy amount of research on ballistics when I was in the ATF Task Force. Along with my on duty shootings I was involved in and testing I've done, 180 just seemed to be the best for what we need as a department. From what I'm hearing, we are transitioning back to the Glock 17 after 15 years of the G22. I've been pushing for that change for a long time. When I came on the job in 2000, we carried the 17 and our hit ratio was much higher.

    The heavy for caliber rounds which are used by most LEA's are softer shooting, penetrate more, quicker back on target and easier on the pistol and shooter.

    Agreed. I want to go back to 124 +P in either the HST or Gold dot.

    155 gr at 1300 fps or 180 gr at 1100 fps. PF's are nearly identical. 165 gr is right there. I'm betting all 3 will open a can of whoop-ass. eta - this is only when loads are pretty hot. Most ammo for 40 S&W isn't loaded to give a 200+ or near 200 PF.

    When I had a .40, I use to carry 165gr gold dots.

    I was in an on duty shooting in 05 with my G27. Hit the bad guy 6 times center mass. The wound channels were rather..large

    I use 135 grain Win Ranger (1200 fps) around the house. If you like 9mm, this is the stuff - it shoots softer than any other .40 ammo I've tried. The 155 and 165 grain carry ammo has the most recoil in my experience. I picked up 3 cases of this 135 grain ammo, which was an overrun on a homeland security contract, at really good price, so I shoot it at the range fairly often.

    For some reason I blindly follow 180 FMJ, plated or JHP... Dont ask me why. I have no explanation that I can defend.

    At least Im honest..

    And the 180's would serve you well if you ever need them, as would 155's or 165's.

    I like the middleweights, both 155 & 165 grain jhp bullets. Of the two, I prefer 155. Either over 180 grain loads for me.

    My favorite in .40 S&W, tho, is the lightweight, full power Cor-Bon 135 grain jhp at 1300fps.. This still gets you awfully close to the old "King of The Street" .357 Magnum 125 grain load, even out of the short G27 barrel when compared to a magnum snubbie. These two loads don't dazzle when judged by "FBI Protocol", but have performed very well on the street.

    Be safe.

    I would focus on shot placement and which round functions in your pistol.
