+P
Can I shoot +P ammo in a Glock? Have 9mm, .40 S&W, and .45ACP?
What about .40 S&W +P in a Kel-Tec sub 2000 carbine?
Also Kimbers in .45 ACP?
Beretta CX4 and Beretta FS92?
What about .40 S&W +P in a Kel-Tec sub 2000 carbine?

9mm and .45 +P are loaded to approximately 10% higher pressure than standard. Good quality guns will handle them just fine. Some say that European spec 9mm is well on the way to US +P anyhow.
There is no SAAMI specification for .40 S&W +P; it is whatever the manufacturer wants to load and label. They won't produce ammuntition that will blow up your gun but if it is really hotter than standard it might beat up the gun with extended use. Or it might just be advertising nonsense. Good luck.0 -

*ALL* modern combat 9mm pistols, including ALL Sig, Beretta, Smith and Wesson, Glock, Taurus, Ruger, H&K, CZ, etc are explicitly rated to handle 9mm+P ammo. Fire all you like and don't worry about it.
Ditto for any good 1911-style pistol and .45ACP+P. The only thing is, if you're going to run lots of +P ammo, you might want to increase the spring weight to reduce slide/frame battering.
.40SW+P is more problematic.
As mentioned, the "standard" .40SW cartridge is *already* loaded to what might be termed +P pressure, and as such there is no SAAMI rating for a ".40SW+P".
I've actually never seen .40SW+P labelled ammo, though I suppose there probably is some of it out there. How "hot" is it loaded? I don't know, and as mentioned, it well may NOT exceed the SAAMI spec. If not, again, it should be safe in any .40SW labelled gun, just as any other .40SW ammo.
If you have some .40SW ammo, its perfectly fair to call the manufacturer, and ask them what pressure it runs at.
The fundamental problem there is that many of the .40SW guns themselves are basically just 9mm guns redesigned to handle the .40SW, and they are already acting near the upper limit of their design capability with "ordinary" .40SW.
For example, the Beretta 92 has an aluminum frame, and is know for lug cracking issues with lots of high pressure 9mm ammo. It would probably be smarter NOT to run overpressure .40SW in the Beretta 96 if you want it to last.
Glock guns are tough as nails, BUT the original .40SW version was just basically a slightly redesigned 9mm. If I remember, right, the very earliest (first gen) .40SW Glocks had issues with some frame pin cracking, and of course we've all heard about "Kaboom"s with .40SW Glocks.
.40SW+P in the Kel-Tec Sub 2000 is also potentially problematic. Kel-Tec pistols are NOT overbuilt, and Kel-Tec specifically recommends AGAINST using +P ammo in its small handguns. I don't know how strong the Sub-2000 is, but that's another polymer heavy gun where I would also advise against trying to push the envelope with overpressure rounds.
Bottom line is that while I doubt that a few boxes of .40SW+P will "blow up" any of the above, if it really does run at 10% (or more) overpressure, I am concerned that lots of it will cause premature wear and could significantly reduce the service life of the gun, especially the Kel-Tec.0 -
Thanks--as usual. 0
