    I agree about .40. I've experienced a case rupture and don't care to repeat it.

    But why would a steady diet of +P+ be a problem in a G26?

    I have never heard of +p+ .40 S&W ammo, only 9x19.

    SAAMI does not recognize 9mm +P+ either.

    Buffalo Bore .40 "+P" from a 1911. The case ruptured at the web right at the ramp. The chamber wasn't fully supported so the fault was entirely mine. It destroyed a magazine floorplate but otherwise no damage done and lesson learned.

    No but it would be unnecessary expense.

    Which does not mean that companies are loading 9mm +P+ at 454 Casull pressures.

    Same applies for .40 +P and .380+P then. Companies made up the designation to sell ammo. Their own way of indicating a "hot" load to the consumer whom does not know the difference.

    I wonder what the MV is for the 9mm 115gr JHP +p+ is from a G17? My chronograph is down.

    Not quite.9mm +P+ has a 30 year track record of being used safely in modern pistols. 40+P and 380+P don't.
    Nope. 9mm pressure had been nudged down by SAAMI to prevent damage to old pistols of questionable strength and quality some of which had been chambered for lower pressure cartridges like 9mm Largo.

    Police Depts demanded hotter 9mm ammo and Winchester, Federal and Remington responded by
    1. providing the ammo,
    2. designating the ammo as +P+,
    3. having the Depts sign a waiver to get it and
    4. not selling the ammo on the open market.

    The process was similar to the introduction of the 38 Super except the Super was intended to be sold on the open market. Colt did not make up the Super designation to sell ammo. They called it 38 Super to differentiate it from the lower pressure 38 ACP and discourage its use in the weaker Colt 1900 pistols.
