    For self defense I use the 68grain Leighi Defense from Underwood ammo, this stuff is so great that Bill Wilson of Wilson combat bought the company .

    The great thing with this ammo is 115 grain ball ammo for practice has same point of impact

    I go the opposite direction and carry 147gr RA9T in my time off. Consistently meets FBI penetration standards from a variety of barrel lengths with above average penetration and expansion, subsonic in a pistol, says “Ranger” right on the box.

    What’s the objective here?

    Ive shot a bunch of 115, 124, and 147. I haven't really seen a difference as far as accuracy goes between grain weight.

    For years my department carried the Speer Gold Dot 124 +P and it was a proven performer. We recently switched the Winchesters new Ranger One 147 grain and it has worked well so far.

    Weight is just weight, gets too much consideration, and is only one of many variables in play.

    My agency has used GD 124+p for the better part of 20+ years. It works extremely well in everything from micro 9’s to full size service weapons. As the guy that use to do all the shooting reviews for the city I can tell you that it works.

    No penetration issues due the lighter weight?

    I like the 68 gr Underwood, too.

    But after that I like a 147 gr bullet pushed hard to maximize expansion and penetration. (Underwood makes a 147 gr Gold Dot +p+)

    This is good to know. Agencies in my area are transitioning back to 9mm from .40 S&W and I considered making this recommendation.

    My carry pistols are comped or ported.
    The efficiency of both are maximized by amount of gas Volume (which isn’t necessarily hand in hand with chamber pressure).
    I carry 124 HST+P or Gold Dot+P. Accuracy with either is nearly identical, shot to shot is quickest in my hands with these.
    A true "Gun Guy" (or gal) should have familiarity and a modicum of proficiency with most all firearms platforms.
