Optic ready…

 

I own both.
Grip texture better and more wrapped around.

Slide is HUGE on the PDP. Anti glare channels deleted on the PDP. No more paddle release M1 so far.

Some say the trigger is different, but I can’t see it. I have a SF Q5, a Polymer Q5 and a PPQ. All have the same trigger. I really disagree that there is a felt difference in the PDP, which some say is a more defined wall. There is zero creep in my three PPQs at the wall, so I don’t know how there can be a more defined wall with less creep.

Glock sights fit the PDP.

There is almost zero "rounding" on the PDP.

While huge, the PDP slide weights the same.

I think the PPQ slide is superior. The PDP is probably the largest slide today. It's really disappointing.

I think the PDP is a disappointing change.

 

The Q4 and Q5 were/are optic ready too. So really disappointing the slide was updated in such a huge way.

PDP-F uses the P99 rectangle size grip (no longer using oval PPQ grip) and removes the finger ribs with a new flatter backstrap. Moves the trigger more reward.

All M2 compact mags fit, except where PDP Pro and Q5 Pro have the funnel jet. Walther states not to use the 18rnd "Full" sized mags with the compact frame.

The P99 20rnd mag fits the P99 and PPQ M1. It has a stopper that stops it going to far up and hitting the extractor. The M2 18rnd mags do not have this and you'll hit your extractor on a compact frame.

 

PDP F-series for a better grip and optic ready option.

 

I believe they still make the PPQ. The PDP is just a very updated evolution of it.

 

The slide of the PDQ is triangular in cross section, so the top is slimmer than the base

I just had mine milled for RMR, and it requires a mounting plate because of the slimness at the top - the screw holes would be too close or on the edge. Thus the optic will over hang the sides of the slide.

Thus the pdp has a wider slide to accommodate less overhang.

 

The PDP is a evolution of the PPQ, although neither has a "graceful slide design" compared to the P99AS,
the beefed up slide was made to accommodate optics.

Now if only Walther would make a all metal version of the P99AS

 

Walther is Replacing its PPQ with the PDP: Comparison of Pistols

The new PDP line of pistols are strong competition for the very many excellent makes and models of pistols available in the market now. This is true of the PPQ M2 models as well and Col Ben is sad to see the PPQ line being discontinued. The PPQ and PDP are excellent and reliable pistols with...

Apparently, Walther discontinued the P99 a year ago, so it's unsurprising they'd follow up with discontinuing the PPQ. It seems they believe they can replace both with their modular PDP model. Walther never seemed interested in really advertising and pushing their 99/PPQ models, nor pursuing the American LE market, comes to that.

Guess that makes my armorer manuals for the P99 variants and the PPQ potential collector items.

Glad I gathered enough spare parts and assemblies to keep my own licensed S&W versions of the P99 serviced and running, hopefully for the rest of my life. Personally, I never cared for the idea of the original 990 (DAO) or QA (S&W's version of the QA was the 990L, but lacking a field-stripping button to decock). The PPQ didn't really interest me, either, as I much preferred the DA/SA option of the original 99.

Time moves on.

 

None of the latest polymer Walthers do anything for me whatsoever.

 

I like the PPQ. I don't have a need for RDS, so the optic cuts ont he PDP doesn't appeal to me.

 

Neither... P99 AS!
I've owned a m1 ppq and a LE m2 longslide.

 

P99 is very much still in production

 

Shot my friends PDP 5 inch this weekend. I loved it. Points more naturally with a mounted red dot than any other optic ready I've tried. Confortable grip. Decent trigger for a striker gun. Locks open on last round (with guns with giant slide stops like this that can be an issue, for me.) I would love to get one some day.

 

It's one of those things that make you go hmmmm?

For every advantage for the PDP they managed to introduce a detriment. Did they have problems with the Q5 optic solution? Not that I am aware of. This is another example supporting my theory about the point system used in the firearms industry (which goes beyond the ATF system). I'm not saying it's PROOF, per se, I'm just saying it's funny coming from both an engineering and aesthetic standpoint. Better grip texture is usually a plus, taking Glock sights is certainly a HUGE advantage, but this bulky slide and lack of a paddle option is perplexing. I can't imagine anyone at Walther was like, "Check out this new and improved slide!". No way.

 

I like the PDP optic system way better than the q5. Having cowitness backup sights is very nice.

 

Is there no way to cowitness your backup sights on a Q5?

 

I own a p99, 2 ppq’s ( 40s&w 4” m2, 9mm 5” m2), and a pdp compact 5”. Of all those the ppq 5” is my favorite and most accurate in my hands. I do like the grip and optics mounting of the pdp better than the other walthers but that’s about where it stops. Walther making the slide so thick on the PDP missed the mark in my opinion. I a world of every gun maker making guns thinner because that’s the trend, Walther makes the thickest 9mm on the market to discontinue and replace the sleek ppq. Don’t get me wrong, I like the PDP but if Walther made the ppq with the pdp grip and mounting system I’d probably not even own a pdp. Trigger is no different than the ppq, as a matter of fact my ppq 5” has a better trigger than my pdp compact 5”. The rail on the PDP is an upgrade to the ppq and p99 as well I guess since there was a few reports of rails breaking here and there on the ppq.

 

I have both a PPQ and a PDP. I have to say that I prefer the PPQ. Mostly due to the slide width but to each his own.

 

Always wanted the PPQ Navy.

 

I thought PDP-F was for self-d/carry. But looking at the size of thing, and the fact that there is no optional slide mounted engage/disengage button -- I do not understand what its purpose. Too small for home-d, too big for carry especially if you happened to be on smaller side size-wise..

 

It's specifically for women (or men with smaller hands). I wouldn't say it's too small for home defense as the 4" model is the size of a Glock 19. It does appear to be a little longer in the reduced circumference grip with a total height—I'm guessing—of about 5.3" (Walther really should do a better job providing the physical dimensions). I'm not sure what you're talking about regarding the optional slide mounted engage/disengage button. That was found on the DA/SA versions of the P99, but it isn't on Walther's striker-fired guns.

 

Believe it's a safety being referenced? Decocker on the P99. But that isn't a "disengage"...

Overlay a PDP-F and a P99 (1994) on handgun hero. The PDP-F is just the P99 grip without the finger grooves and a straight backstrap. Moves away from PPQ oval grip.

The hump on the P99 is very pronounced. I tried adding a PPQ backstrap to the P99 to calm it down. They don't fit.

So while an improvement, it's basically the same grip with no effort by Walther to improve (which they did).
