Check the owner's manual. Walther does not recommend +P and +P+ ammo in its pistols. You'll also find many references to this by running a search; it's been covered in a number of threads.
It can handle +p ammo, like has said it will require more mnx. Of course 95% of the ammo that comes out of my PPX, hell, any of my handguns actually, is FMJ. I normally shoot +p at first or +p+ depending on the gun when I first get it to make sure the gun runs with it.

It'll handle it, all right, right up until the time when it doesn't. We've seen those photos, some of which have been posted on this very forum. But it's your pistol, your call ... even if Walther specifically advises against it.

Yeah? Show us those PPX's that have failed with +p ammo then. Hey, I'm pretty sure all guns work until they don't lol Not a good argument :D That makes me laugh. The PPX can handle it, end of story.

I was referencing Walther firearms/firearms in general that advise against using puffed-up ammo, and yeah, we have seen those photos. Right here, in fact. But again, it's your pistol and your call. Have at it and have some fun with it. Post up some photos when the time comes. :)

Being able to put some accurate quality JHPs on whatever threat arises is all I want to do but hopefully never have to. I have no plans on using overpressure ammo in my PPX, but it is mine. Those that choose to do so, will and probably have always used it. Maybe they'll have more repairs down the road, but it's their PPX. One day maybe we'll see some hardcore results for this gun using that type ammo. Until then, happy shooting!

I will certainly do so though worried about it, I am not. Some of us crawl through life, some of us like to stand upright and walk, unafraid. I think I can risk this one lol Gotta love the internet :rolleyes:

Agreed. 'Cause you never know what you are going to get on the other side of the discussion. This exchange is a good example.

The caution about +P and +P+ ammo is worth heeding, for those with an open mind and a bit of respect for the engineers who built the pistols, anyway. Bad things can (and do) happen at times if the recommendations aren't followed, dspite the number of emoticons and LOLs attached to a note of dismissal ... and again, it's your pistol: do what you want.

I can find Glocks, Sigs, etc with the same sort of damage...all cleared for +p and +p+. So there's one failure, out of how many? So I shot 100 rounds of 115gr FMJ and 50 rounds of 124gr +p today. So worried the gun was going to blow up or completely shatter into 1000 pieces!!! Damn, I was lucky!!

For the range? Anything you can find.

For self defense? Consider doing some reading and make an informed decision: Best Choices for Self Defense Ammo

Shouldn't matter that it's coming out of a PPX, 9mm is 9mm is 9mm is 9mm. Not much really changes coming from a PPX as it would a PPQ or P99. What matters is comfort with the platform, accuracy, as well as reliability.

I'm with searcher: steer clear of the +P+, there is just not a need. Even though Walther "kind of" says +P is "alright", I still avoid it.

Might as well ask what oil works best-- check that link and do some of your own reading, then get out and see what works!

Made my regular Saturday morning visit to Walmart today and they had 9mm ammo just in so I picked some more Federal. I have enough FMJs now to practice with, time to check into some more JHPs I've been reading about. I'll see what they have at the Gun Show that's coming to town next weekend. Hopefully they'll have good stuff that's not too high.

Ready to hit the range!

In my humble opinion this gun manufacturers act irresponsibly when they clear for +p+.
When I take a look on the SAAMI specs there is written that the pressure is rated at 35000 psi at normal load and 38500 psi for +p loads.
+p+ is not specified there. So all loads above 38500 psi are +p+. Because there is no exact specification for +p+ how can they guarantee that their guns can withstand this pressures?

Additionally here in Europe we don't use SAAMI. Here we have C.I.P. (Commission Internationale Permanente) - the pressures are different to SAAMI specs. (9mm Luger is rated at 34080 psi). So ammo made in the U.S. will wear a gun more than European ammo - even at standard load. Of course Walther (and other manufacturers) tested their guns also at SAAMI specifications but nonetheless +p+ is dangerous - especially when it is used in european guns, because the pressure limits are more exceeded than in U.S. guns.

Okay , it seems that S&W issues the same exact warning about using +p and +p+ ammunition in their M&P handguns. The point being that it's just a simple warning that +p ammo breaks a gun down quicker. It's worth noting but nothing to be overly concerned about if you choose +p ammo for self defense.

Searcher,
It sounds like you do agree with using +P for self-defense, just not on any degree of regularity. But correct me if I'm wrong.

Although police departments that are still issuing 9mm generally use 124 gr +P, some still use 147 gr, and have had good results at stopping bad guys. From my research, I still think that 124 gr +P is the most reliable round for stopping power in the 9mm, if you consider both ballistic gel testing and reports from the street. There is no difference between a police shooting and a civilian shooting with the exception of barriers like cars / windows.

Do your own research, but I have come to the following conclusion:
1) Regulary shoot standard pressure FMJ.
2) Carry 124 gr +p (alternate is 147 gr standard pressure) after shooting at least 100 rounds to make sure it cycles in your gun without malfunctions. After 6 to 9 months on the shelf, I then shoot my carry ammo and replace it with newer stock. So I'm shooting +p at the rate of 50 to 100 rounds every 6 months. Sometimes, I just donate it to my 21 year old son, who thinks his Glock 19 is un-breakable :).

Most of your manufacturers advise against the use of +P+ ammunition. Most also warn of excessive wear possible with +P ammo but they don't say you can't use it. It's just a warning your gun might wear out sooner. Both PPX and PPQ manuals say the same thing. The write up on the first page of the threat saying that walther says you can't use +P ammo is not accurate.
