    I have always shot +p ammo (Speer Gold Dot, Remington Golden Sabre) for SD in my G19. I do not shoot a lot of it, but enough to make sure it feeds, ejects, etc. properly. I have not shot +p+ ammo out of my G19, but would like to do so (Buffalo Bore in particular). I know it is fine with the Gen 4 pistols and the stiffer guide rod spring, but is it harmless to the pistol to shoot it in a Gen 3 G19 with stock everything. Again, I don't shoot lots of SD rounds out of it, but don't want to shoot something I shouldn't. In fact, I want to be confident that if I wanted to, I could shoot as many SD rounds out of it as I would like without any adverse effects to the pistol. Chime in experts!

    ALL 9mm Glockas are safe with 9mm +p+ ammo.

  3. I tend to agree that any +P+ 9mm ammo is OK in any Glock. However I would still limit my use of +P+ ammo to make sure it feeds and shoots where you point it. Maybe 150 or 200 rounds a year maximum is what I would do.

    I would stop at the +P loads myself in a Glock.

    I can't find a reason to do that. I've fired +P+ with no problems in my 17.

    Let's put this in perspective, a regular .40 with an unsupported chamber is more or less 35,000 PSI. A regular 9 mm. is around 36,000, and +P about 37,000 give or take up to 38,500 by SAAMI specs but no big company loads these that I know of. +P+ is not specified by SAAMI, but there is no way it is above the 40,000 PSI that hot 357 sigs are loaded at, also with an unsupported chamber.

    It is the same frame for all pistols, and the 9mm has the benefit of thicker metal in the chamber, so I ask--why not +P+ ?

    BTW, pressure testing in these pistols goes all the way up to 50,000 PSI I think.

    I have two questions;

    1. What type of bullet does BB use in this +P+?

    2. What is the reason for loading it to +P+?

    The 9mm Glocks were designed for shooting nato 9mm,so yes +p+ is ok for the 9mm glocks.
  8. I thought 9mm Nato was basically +P!!!
    I have never heard that 9mm Nato is +P+?

    I think a Glock can handle +P+ in any caliber on a limited basis, 150 to 200 rounds per year approx. IMO.

    I found out that generally speaking, BB (and many others) use the Speer GD bullet. So that answers my first question for the most part.

    But my second question remains unanswered. What is the reason for loading it to +P+?

    Some like speed.

    Look at some of the other manufacturers out there:

    Winchester's Ranger Line: 115+P+ 127+P+
    Federal's LE Line: 115+P+ 124+P+
    Remington's Line: 115+P+

    Light and fast…Heavy and slow. I believe it's a niche that's being filled.

    Me, I like medium weight and fast for the 9mm. The 127+P+ Ranger is my pill of choice.

    I can see this, but I'm wondering....why? A Speer GD is designed to function within a velocity window. The 124 for example in standard pressure I believe is 1150fps and the +P 1220fps. The 115 is 1200fps the last time I looked at the ballistics. So what would be the purpose of driving it 200fps faster when it is designed to function at a slower velocity?

    Couldn't honestly tell you. I do know that Speer breaks their own velocity requirements for the 115 Gr. bullet.

    115 Gr. +P+ Speer GDHP: Consistently hit 1305 (Avg.) from my G17. 1275 from my G19.

    The higher the speed the greater the temporary/secondary cavity and the more "rifle like" the wound will be. Gold Dots are tough bullets, the worst that happens when you go over velocity is over-expansion, unless you start getting extreme (like 155 grain 10mm rounds at full power) then the bullet starts to fragment. There again though, this isn't really a problem provided there is sufficient penetration depth.

    Many LE agencies issued +p+ rounds for many years without problems. Its ok in most modern duty firearms.

    My G17 is currently loaded with Win 9mm 115gr JHP +p+.
