G. M., To my knowledge,I don't have any modern 9MMs that are not recommended for 9MM +P. Some of the other members here can likely supply that information. From personal experience though, I have used thousands of rounds of +P+, +P, NATO and equivalent reloads in a variety of 9MM pistols, revolvers and carbines. None have ever beat themselves to death, broke, bent, cracked or deformed any parts. I don't have any concern in using the ammo I mentioned in quality firearms in good repair. Of course, a prudent person would not use +P+, or even +P, in firearms of dubious heritage and/or condition.
BTW, I have chronographed quite a variety of 9MM ammo in different types of firearms over a good many years. This included Remington, Winchester and Federal 9MM +P+. Yes, +P+ velocities are higher than most +P ammo. CorBon 9MM +P, often as not though, equals or exceeds major manufacturers' +P+ velocities. Apparently there are enough law enforcement agencies that have determined there is value in 9MM +P+ to keep it production. It has been my experience that law enforcement agencies buying all kinds of equipment and supplies, including millions of rounds of ammunition every year, do not tend to buy equipment and supplies, including ammunition, likely to inadvertently injure officers or the public, or damage or significantly reduce the service life of department or officer owned firearms........ymmv
