    My thoughts ...

    The heavier bullet, if at identical velocities, presuming similar expansion (ie, same bullet design/tuning), striking the same target in the same manner. Simple physics, I'd say.

    But each bullet's different, as is the target conditions (angle of entry, whether it strikes bone or tissue, etc). So, in practice, it'd probably be close depending on the performance of the given bullet in similar conditions. Might well be that the edge is with the smaller and lighter bullet under certain conditions. ie, With a Speer GD versus a Winchester Ranger-T bullet. Short of a head-on-head comparo, it's hard to say.

    Personally, I'd have a hard time turning away from a .357SIG @ 1500fps in 125gr, if I had a choice in two identical pistols in those calibers.

    Thank-you Sir for your thoughts. Having both a 40 caliber & .357 Sig barrels its sure interesting concept.

    That 135gr gives a good pop.

    I felt the recoil in my hand every time I pulled the trigger, the recoil of the 165/180gr of Underwood and other main stream manufacturers feel normal but the 135gr doesn't. At least not to me.

    These are two subjective and perhaps different questions.

    If "Hit hardest"= likely to penetrate deepest, then the heavier projectile. In that case, why would you not choose the 180gr. round?
    If most damage= largest wound channel, then a wider projectile and deeper channel. Again, the .40, but again in 180gr.

    The .357sig is a fine caliber, but I feel that it is a niche round. It has great advantages in specific applications. The cost, availability, and narrow situational advantage dissuades me.

    Big brother is watching and listening to what is put on these forums. Questions like this can come back to bite you. Just my 2 cents.

    The tests I have seen show that a135 grain 40 going that fast lacks penetration. Tnoutdoords9 has tested a lot of ammo and you need to look see for yourself. The .40S&W in +P with 155 to 165 grain bullet seems to come close to the all out 357Sig.

    I'd probably opt for the 357 Sig. It's pretty close to ammo used by a number of law enforcement agencies, who I hear like that round a lot. Same bullet I believe, Speer Gold Dot, right? And I think it's going about 150 fps faster in the Underwood version.

    "Hits hardest and "do most damage" comprise some sort of death-wish for deadly violent assailants, or some macabre view that injury of assailants is desirable?

    Seems clear to me, and to anyone seeking defense arming against predation, that effective means of withstanding attempts on our lives is a valid desire. That takes ammo capable of getting that job done, the job that the statutes clearly justify.

    I can see the point, but I have a hard time believing the claim would be anything other than a weak and easily-thwarted attempt to vilify someone who's justifiability according to the statutes is iron-clad in a situation warranting stopping the violence of a violent felon bent on death and destruction, particularly when the body of work (postings) of most everyone is along the lines of shooting only where needed, shooting to stop the felony violence against us, not desiring to become involved in any such violence, etc etc .

    The one you can put center mass. (Sorry, had to).

    If you haven't, check out tnoutdoors9 on youtube, he has a bunch of underwood ammo tests including the 125gr round in .357 sig. IIRC out of a Glock 32 it was actually over 1500fps. WOW.

    EDIT: Yep, I was right. 5 shot avg for that test was 1511 fps, look what it does to that poor gold dot bullet!

    You could get an non-subjective answer if you ask do you prefer dark chocolate vs dark chocolate with cherries!

    Both are chocolate but it would depend on your taste! Lucky for me that I have both a 40 S&W barrel and a .357 Sig barrel. So my Opinion is both would do the job with proper shot placement!

    You are free to ask questions, however this thread's question (another analogy) it is asking which is better a quarter. The one from the Denver mint or one from the San Francisco mint?

    Answer is of course the one from the Happy** Bay Mint, I.e., San Francisco mint!

    ** Happy is synonymous with the word I can't use and be PC!
