+P Ammo in a Glock 17?

No Glock haters please.

I wanted to get a new box of HD ammo the other day (my last box of HD ammo is 15 yrs old), and a LGS sold me Hornady Critical Duty 9mm +P 135 grain.
I normally shoot 124 gr. 115 for plinking.

Is +P 135 gr. too much for my Glock 17?

I was going to take it out to shoot a mag or two and see how they feed/fire, but I am finding conflicting info all over the interwebs.

What do y'all think?

I have fired +P ammo in my G17, G19 and G22 many times. I've never fired the ammo you mentioned but I've fired a lot of Winchester PDX1, 9mm, 124gr and 147gr with out a problem. I've also fired Winchester PDX1, +P, 180gr and 165gr, .40S&W out of my G22, those ones really make my G22 bark. When I say a lot I mean 100 or so threw each gun. Enough to make sure they function well, which they did indeed. The Winchester PDX1, 124gr +P is extremely accurate. It's not top of the line but it inexpisive and has work very well in my experience. I know that's not what you're asking but yes Glocks can shoot +P ammo.

Glocks like most guns can handle +P just fine.

A little more powder/pressure and stress on the gun but they are designed to last.

Put a few boxes of chosen ammo through your gun to know POI and that your gun runs that particular ammo and have at it.

And I'm sure your conflicting info was guys spouting kabooms. Which are supposedly so common but it's funny you only see the same 6 kabooms posted. Being so coming youd figure there would be more photos right

Good your asking to be on the save side tho.

Keep in mind that the Glock 17 was designed as a Military pistol. It was specifically designed to meet NATO spec. NATO spec 9mm ammunition is a bit hotter that SAMMI spec 9mm ammunition. NATO spec is very close to SAMMI spec +P. Glock endorses the use of all SAMMI and NATO spec ammunition, including +P.

I have personally shot thousands of rounds of both NATO spec 9mm and Sammi +P in my 34. No issues of any kind.

Don't do it, the Glock will blow up!!!

The only problem I've had is when reloading cases that were fired with hot loads thru a Glock barrel. I've had a few of them rupture the next time out.

Taken from the FAQs on Glock ID where Glock responded to a question about using +p and +p+ "Glock suggests using ammunition that is manufactured and meets SAAMI or industry specifications. If you are not sure the ammunition brand or type you choose is safe for use, call the ammunition manufacturer and ask if the product meets SAAMI guidelines before using it in you firearm. Some +P ammunition meets these guidelines, +P+ normally does not. This ammunition may generate a higher pressure over the standard loadings, and may shorten the component life of your firearm. "

Hope this clears up your question.

As a Glock owner since the 90's with tens of thousands of rounds experience, I will tell you it's 100% fine with a properly functioning 9mm Glock. Hell I have a few mags of HST in 147gr +P loaded up.

Sounds like your reloading problem

I don't know of any company that promites the use of +P+ since, as far as I know, there is no standardization of +P+.

You will feel the recoil difference but it should be fine.

The Glock is a plastic gun designed to allow terrorists to sneak them thru airport metal detectors. Do not use +P ammo in plastic guns!

Don't discount that early unsupported Glock chambers cause case bulging with hot loads. Resizing a bulged case work hardens it and can cause it to crack or rupture much sooner than a non bulged case.

Essentially the same info conveyed when I took the armorer's class.

I would trust any name-brand, factory-manufactured +P ammo in a Glock. Even most (name-brand, factory-manufactured) +P+ is probably fine.

What is scary is using any +P+ ammo from questionable sources, including boutique brands and custom hand-loads.

9mm Glocks have never been known for this issue since the dozen I've owned since 1998, and the newest Glocks have pretty tight chambers.

Not a reloading problem. It's a Glock chamber issue.

Glock fanboys can't handle facts.
