Hello all,
I had heard in the past that you shouldn't fire +P ammo out of Glocks. Is this true? I was interested in firing some 9mm +P out of my G19.
Any thoughts?
Thanks

Re: +P ammo in Glock?
It's safe, but like all +P it increases wear and tear on the gun. Many manufacturers don't recommend +P.

Re: +P ammo in Glock?
A Glock 19 will shoot all the +P ammo you want to feed it just fine with no ill effects. I can't imagine any reputable source stating that you shouldn't fire +P ammo in a Glock 19.

Re: +P ammo in Glock?
I remember reading some years ago that Glock designed the 17 to be compatible with German military issue subgun ammo, which was loaded hotter than NATO spec (which is approximately +P).
Whether that's true or not I do not know.

Re: +P ammo in Glock?
The Glock 17 was designed to meet Austrian Military requirements/specifications for a new pistol to replace their WWII vintage service pistol, the Walther P38.
Here is the specific requirement that relates to cartridge pressure:
"After firing 15,000 rounds of standard ammunition, the pistol will be inspected for wear. The pistol will then be used to fire an overpressure test cartridge generating 5,000 bar (72,518 psi) (the normal maximum operating pressure Pmax for the 9 mm NATO is rated at 2,520 bar (36,550 psi)). The critical components must continue to function properly and be up to specifications, otherwise the pistol will be disqualified."
9mm +P ammo is a little hotter than NATO spec -- it's a max of 38,500 psi as I recall.
According to Wikipedia, here are the other requirements:
The design has to be self-loading.
The pistol must fire the NATO-standard 9x19mm Parabellum cartridge.
The magazines would not require any means of assistance for loading.
The magazines must have a minimum capacity of 8 rounds.
All actions necessary to prepare the pistol for firing and any actions required after firing must be done single-handed, either right- or left-handed.
The pistol must be absolutely secure against accidental discharge from shock, stroke and drops from a height of 2 meters onto a steel plate.
Disassembly of the main parts for maintenance and reassembling must be possible without the use of any tools.
Maintenance and cleaning of the pistol must be accomplished without the use of tools.
The pistol's construction may not exceed 58 individual parts (equivalent of a P38).
Gauges, measuring and precise testing devices must not be necessary for the long-term maintenance of the pistol.
The manufacturer is required to provide the Ministry of Defence with a complete set of engineering drawings and exploded views. These must be supplied with all the relevant details for the production of the pistol.
All components must be fully interchangeable between pistols.
No more than 20 malfunctions are permitted during the first 10,000 rounds fired, not even minor jams that can be cleared without the use of any tools.
When handled properly, under no circumstances may the user be endangered by case ejection.
The muzzle energy must be at least 441.5 J when firing a 9mm S-round/P-08 Hirtenberger AG.
Pistols scoring less than 70% of the total available points will not be considered for military use.
