    .45acp is more powerful than a .357mag?

    I just watched a YT vid on the Ruger Sp101 3" (I'm wanting one pretty bad), it was by Midway USA. And on their "One shot stop" board the .357mag had the same rating as a .40 S&W 180gr and .45acp but rated the .45acp +p 185gr and I think 165gr +p .40 S&W to be more powerful than the .357mag 125gr. Now I dont believe in any handgun having a "One shot stop" cartridge but I would think that the .357mag would whip any .40 S&W or .45acp. I am far from a ballistic expert but anybody agree with this?
    I carry a .357mag because no one bickers about the .357mag being "enough".

    Keep in mind I have a whole bunch of calibers including .40 S&W and the .45acp, I dont own a .357mag yet. So I'm not partial to one of my guns or calibers. Logic just tells me that a .357mag is a bad son-of-a-gun.

    Caliber wars, Chapter 127...

    Over the course of modern handgun history - say from post-WWII days - the .357 magnum in 125 grain JHP configuration probably has the best record in police use in terms of fight-stopping ability. However, with wheelguns out of mainstream cop use for nearly a generation now, the auto pistol calibers have caught up and the .40 S&W is the most commonly used service round in the US today. Ergo, more chances for that round to do well. And the performance of the .45 ACP, even in FMJ, is nearly legendary. But fundamentally, the differences in downrange performance among the three loads mentioned isn't big enough to write home about... it's almost splitting hairs. Really comes down to how you define "powerful" and "one shot stop."

    FYI, you mention a .40 +P round. Note that there is no SAAMI spec for +P pressure in .40 S&W, although Buffalo Bore apparently markets a .40 +P.

    They do the same thing in different ways. The 357 uses speed to create energy for penetration and proper bullet expansion. The 45 doesnt need speed, it uses its weight to "bore" a straight line hole to where it needs to be, and is large enough in diameter that expansion is not needed. Like mentioned above, there is no saami spec for 40+p.

    LOL, I certainly wasnt trying to start a caliber war! .40 S&W +p was obviously a mistake on my part. I certainly dont think that one caliber is better than another, just one is better than another for the shooter to determine. I guess I just always kinda thought that the .357mag and .44mag were the end all be all in hand guns and let the others bicker it out! Its kinda like "what is better, the 9mm/.40/.45, but there was no second guessing the magnum calibers. i guess I'm wrong........AGAIN! :)

    I really LIKE Larry Potterfield from MIDWAYUSA. He is a dard good man in so many ways.
    But, I always chuckle a bit when he "rates" handgun KNOCK DOWN POWER.

    My main carry guns are 1911's in .45 acp. But I also own a 3 inch Sp101 .357 mag & shoot it often. I love it. I call it my "town & country" gun, thats what I carry when upland & waterfowl hunting. So when commuting to & from hunting area's I still have a very good ccw.

    Which is more powefull? Look at it this way, in my state (kansas) the .357 mag is a legal deer round, the .40 S&W & .45 ACP are not. Yes my SP 101 goes deer hunting with me not to hunt deer with but so I can have a legal ccw with me. However a close range broadside lung shot with my Fed. 158 grain hydra-shocks would not be out of the question.


    When I'm bumbing down a rocky mountain trail the little Ruger most always gets the nod. Lightweight reliable & powerfull & very accurate from such a small package.

    As for the manstopper debate, whether .9mm .40 .45 10 mm .38 .41 mag .44 mag .45 colt or .357 they all will work if you make center hits.

    Funny you mention that at this time. I have watermelons and cantaloupes coming out of my ears from my garden and can't even give them away, so! A couple days ago I thought I would have some fun and give some of the remains to my chickens as a treat. I was shooting (2) .45 Kimbers and my S&W 686 plus .357 magnum. Shooting HP ammunition for best effect. Shot 16 HP self defense rounds with the Kimbers, and 7 rounds with my .357. After all, PD HP rounds are expensive and the chickens can eat only so much! My results were unexpected! The .45's did more damage than the .357's. Made tomato juice out of a few tomatoes for some lucky ants.

    I always carry a .45 ACP as a backup for one of my two .380's.
