    HUH ? I can empty a 7 shot , 2" barrel .357 revolver at 60 feet into a 3" circle in 2.8 -3.5 seconds. So, I think I can disprove that theory real quick.

    Do they say what pistols they are using to get those results?

    Common loadings for a .357 mag are much higher. One load I use for hunting is over 700 ft lbs of energy and it is not at the absolute max.

    Can followup shots be slower with full blown .357 mag, yes, but with the right gun and shooter they should not be much different. Heavy loads of 38 +P in a lightweight revolver might not be fast on followup and are definately not fun to shoot in some cases.

    I choose a .357, the wife chooses a gun 38 capable of +P. My choice, my gun, her choice her gun.
    That is true, unless you are talking about a snub nose, which is what the poster is considering/bought. Quoted ballistics for 357Mags are most always from a 6 or 8 inch barrel, whereas a .38 is usually from a 4 inch. Now consider the fact that a 357Mag loses 1/3 t0 1/2 it's energy (ft/lbs) when you go from a 6-8 inch barrel to a 2-3 inch barrel. A .38 doesn't lose as much, because it isn't a magnum and doesn't need the longer barrels to reach the velocity to achieve "magnum" power.

    So, to disagree with most every other poster here-With a snub nose, which was specifically mentioned, there really is no difference between a +P .38 and 357Mag round.

    Consider Speer ballistic chart shows the 357Mag out of a 2" barrel attains 294 ft/lbs compared to a 38+P out of a two inch barrel at 222 ft/lbs. Nowhere near 300 ftlbs of difference, more like 70 ft/lbs. Now here is a real kicker, a 3" .38+P can actually obtain better ballistics than a 2" 357Mag.

    Without the needed barrel lenght, all that magnum energy is actually a waste and detrimental due to the added recoil and muzzle flash, that is why the short 357s have such a large muzzle blast.

    Don't get me wrong, I love 357s, they just aren't what we think they are out of snubbies.
    My heroes are Veterans and My Father (who was a veteran).

    I believe prayer and the Pledge of Allegiance should have REMAINED in schools, and the Ten Commandments should have REMAINED in schools, courthouses, and everywhere else it was before the ACLU got involved.
