    Focusing on the caliber only, and not thinkin about revolver vs semi auto, but bullet weight and velocity. Concealment doesnt matter in this case. What would be better all around, as a defensive and offensive manstopper and why. Give some cartridge examples if you can.

    If you look simply at energy delivered to the target, then .357 wins most of the time.

    Federal's top .45 and .357 rounds muzzle energy for example:

    125gr .357 - 576 ft/lbs
    165gr .45 - 476 ft/lbs

    What ever one you shoot best. Hitting the target is far more important than ballistics.

    it does

    but then its a question of slower and more heavy vs lighter and faster. I assume 357 does better at range. Could there be much difference at 25-50 yards? 4 inch barrel suppose.

    The ballistics in my example cross at about 100 yds... well beyond effective range. The larger bullet will hold energy longer, but it's inconsequential for these two rounds.

    As stated, both will bring someone down riki-tic, but only if you can hit your target. Please give actual confirmation that you can proficiently and consistently, hit a man sized target, center mass or a head shot @ 25-50 yards. Most SD encounters usually take place between 2-7 yards.

    I would not feel poorly armed with either, and I carry one or the other daily. As the man said, whichever you shoot the best. Both have an excellent track record for stopping bad guys. Quickly.

    If concealment were no issue I would go with the .357 hands down. I find mine to be much more accurate than any auto I've ever handled. Plus it has never failed to go bang. That being said, concealment and ease of carry is an issue. So I carry either my Kimber Compact or my PF9 more often than not.

    I personally like putting bigger holes in things so I prefer the 45 ACP.
    The best ballistic data I found is as follows,
    Buffalo Bore 357 magnum 158gr - 1485 ft/s = 774 ft/lbs.
    Double Tap 45 ACP 185gr - 1225 ft/s = 616 ft/lbs.
    Buffalo Bore 45 Super 185gr - 1300 ft/s = 694 ft/lbs (may need to modify pistol).
    Remember, bigger holes bleed faster!
    You can also split the difference by choosing the 10mm,
    Double Tap 10mm 165gr - 1425 ft/s = 744 ft/lbs.
    Since your only factor was ballistics, I'd have you lean towards the .357 S&W Magnum.

    25-50 yards isn't personal defense, it's hunting.

    Quoted for truth!

    Explain to the nice policeman why you HAD to fire when the fella attacking you was 25-50 yards away. I'm sure the DA will also be really sympathetic...

    The 357 mag in 125 gr HP is supposed to a stopper that wont over penetrate. The 158 has a tendency blow through. I carry Win PD 110 gr HP In my 2" SP101. It is better than 38 spl+P and is very controllable. If I want something hotter I go the 125 gr HP. The 158 gr is not much fun in a snubbie. 4" barrel 357 I would use the 125 gr loads unless I am out hiking and might meet up with a critter.
    I like the 230 gr HP in the 45. No specific reason except it is what I have always used. I have though about trying some 185's but never got past the thinking stage.

    I don't think you could go wrong with either. They both have a great track record in the BG stopping area. I would go with whichever one you can shoot quickly and accurately.

    My .45 holds 13 rounds, while my .357 only holds 6 rounds; i would go with my .45.

    Now that is important to keep in mind.

    My SP101 holds 5 rounds. 5 x 576ft/lbs = 2,880 ft/lbs of energy to have at the ready.

    A .45 holding 10 rounds... 10 x 476ft/lbs = 4,760 ft/lbs of energy to have at the ready.

    Yeah, what he said!
    My 1911 holds 14 rounds of 200gr Speer Gold Dots,
    Thats 1080 ft/s giving 518 ft/lbs x 14 = 7252 ft/lbs of energy upon the target.

    Its a good point my XDm 45 = 13+1, whereas the largest .357 is 8.

    Let us not discount the impact of the empty firearm, should the shooter choose to use it as a last-ditch projectile; shooterdude could have one heck of an arm.

    :D
