Ammo ratings

[BACKTOSHOOTING]

I have a couple of questions about ammo.

1- What dose it mean exactly when the ammo is rated +/ +P/ and +P+.

Also why do the manufactureres of the firearms send spent caseings with the guns, is it for ballistic testing aginst the gun ?

The +P stuff is a hotter load (higher pressure) than the standard.

[hyperion.excal]

+p is hot load

+p+ = hotter load

+ = more , p = powder

Be sure your gun is rated to handle +P or higher ammo! If you are not sure you can always check with a dealer or the manufacturer.

Yes as to all others have said +p is a hotter load and, yes make sure your firearm can handle it!

Not to thread jack, but I read somewhere that the +p+ means little(I can't remember where I read this but it was a paper magazine or the like). Or was that because SAMMI does not recognize the +p+?

The +P designation on ammo is a reference to SAAMI/ANSI pressure specs. In the case of 9mm, a +P runs about 10% higher pressure than a 'standard' load in the same bullet weight. To the best of my knowledge, SAAMI does not provide a pressure spec for +P+. Inference would suggest +P+ operates beyond the range or max pressure value of a +P load. The SAAMI site has spec details.

At a more functional level, the higher pressure loads are associated with higher velocities (keeping bullet weight constant).

I have a glock 17 gen 3 stock barrel and a LW 6" barrel for it.

I am in DROS on a glock 21 gen 3 and a kimber tle ss1911

The glock 21 will be mostly for HD.

Your thoughts please

The +P designation as used by SAMMI is for a cartridge that is dimensionally identical to the original but loaded to a higher pressure. For example the 9mm is a 35,000 psi cartridge and +P is 38,500 PSI. Similarly, the 38 spl is 17,000 PSI and 18,500 PSI for +P. Even the venerable old 45 ACP has its +P designation raising the pressure from 21,000 PSI to 23,000 PSI.

There is no official +P+ standard so you pays your money and you takes your chances. However, in today's litigious society I doubt too many guns blow up from +P+ ammo.

NATO pressure standards may be different than SAMMI. The NATO 9mm spec limits pressure to 36,500. The 5.56mm NATO is 62,000 PSI whereas SAMMI standard for the .223 Remington is 55,000 psi. Because they are measured in different places, the difference is not as bad as it looks.

Can a Glock 19 Gen3 handle P+?

[tundraotto]

Can a Glock 19 Gen3 handle P+?

mine handles +P+ 9BPLE regularly....dont know if "its rated for it".

[AK all day]

Have shot plenty of +p+ Winchester ranger out of my Glock 17 gen 3.

As a recently certified Glock armorer, I asked that specific question, at the armorer’s class. The factory representative stated that all Glock pistols are manufactured for long term use with both NATO standard and + p ammunition on a regular basis. Think about it for a moment the Glock 17 was designed originally as a Military duty pistol for NATO troops. As stated above, on a personal note I have shot many 1000's of rounds of +P+ ammunition out of both my 17 and my 34. Both are in good shape, no problems of any sort noted. .

Good stuf to know about the Glocks,

The Kimber SS TLE is new too me and dont know hardly anything about them outher than they shoot real nice [ I have shot them ] and I might end up useing it for HD, not sure yet.

what do you guys think for the kimber, Thanks
