May I ask, is the grip feel of the P99 so bad that you simply can't live with it unless it felt like a PPQ frame?

According to a discussion I had with a local instructor who has won an Emmy for his segments on the nightly news here, modifying defensive pistols is a bad idea. I was told, by him, that after a defensive shooting, it is not unheard of for the pistol used to be sent back to the manufacturer for inspection, to see if any alterations were done to the pistol. Do you really want this as a possibility if you ever have to use this hybrid pistol defensively, and all so that your grip can feel just a little different than a P99?
Thats a good question... I usually add Hogue Handall finger groove grip sleeves to my P99s. Could that be considered a 'modification'- I don't know. In theory, I could see Atty X making the argument, 'you have modified the stock P99 so you could shoot my client easier with that rubber sleeve.'

My argument is-its about a better grip for me. I've only upgraded the frame. I may have a touch of arthritis, I have 'improved the grip' w/o a grip sleeve with a PPQ frame. Yes- we are possibly splitting legal hairs here.

Re; Modifying a defensive pistol is a bad idea... Could it be considered "not changed from the 'factory' function of trigger, sear, etc." VS. 'Modified' by setting a hair trigger or hammer or etc. etc. That to me is a definite no no for a defensive pistol. Yes- it could be considered not 'original' now but also not turned into a race gun.

Just my $.02. :)

The simple fix is for Walther to produce a P99 M1 and M2. :D

I guess I forgot to mention that I'm old school and stuck in the DA/SA decocker world.

Awesome, thank you. If you get a change, would you mind showing where you trimmed the trigger area on the PPQ frame?
When you install the P99 trigger and pull it slightly you'll see where it begins to rub against the frame. Just take an exacto knife and shave off where it rubs in that frame area. You'll see a difference in the moldings from PPQ frame to P99 frame in that space side by side.

Also, borrow or buy a cheap harbor freight arbor press. It make pushing out the frame roll pins a lot easier. No punches w/ a hammer. A gentle 'crank' with a punch on the press and the pins push right out.

Take care,
-P

Fair point. But I’m not really concerned about using this particular pistol as a defensive weapon. Even if I were, I think In such a scenario my defense team would be able to demonstrate that my goal was to make the weapon safer.

As far as the “why” I have no issue with the P99’s grip— but I’d really like a full 1913 rail and perhaps an optics mount like the Q4 Tac. I don’t think you can do that with the P99 slide because the decocker would get in the way. I don’t think I’d really need the decocker, but from the mod I would hope to gain the AS mode as well as second-strike capability.

I was just searching online for a long barrel MR9 last night. They're hard to find.
Yeah, I know. I bought the last one. :D

The 4.5" has been a ghost for about 6 months. The 4" version can be found sometimes, but now, they're wanting a premium price.

I shoulda bought 2 of the 4.5's when I had a chance. I feel like such a DA now. :D

Darn you OF.


I came across this last night.....


https://www.sportsmans.com/shooting-gear-gun-supplies/handguns/magnum-research-mr9-eagle-9mm-luger-4in-stainless-pistol-151-rounds/p/1459838


If they ACTUALLY have it, and you want a 4", that's a great price.
I'm thinkin' that's what the Fonz needs.

As for me, I just built one of these (see below). Will turn a regular squirrel into Rocky the Flying Squirrel in the blink of ole Bull Winkles eye. That's a 2.5" barrel, which accepts a tennis ball....80 PSI and vroooommm. There's no decocker and no safety...just a SAO trigger.

The squirrels harass my dogs and eat my patio furniture, I harass the squirrels. :D

The barrel is removable. I've used adaptors to allow me to build and use different size/diameter barrels...just takes a minute to unscrew one and screw on another.

Also built another one using a 3" sprinkler valve, a 4' long tank and a 5' barrel. When I fire that one downrange, the tennis ball just disappears, arcing thru the sky, much like an artillery shot.

Good timing OF.


I just had the entire sprinkler system rebuilt on the house here in Coppell (most PVC lines replaced, new valves/solenoids, main valve assembly too). Went with the Rachio Wi-Fi online App controller, with 2 high volume sprinkler heads pointed at the front door (on their own zone, had an extra one, wanted to use it).
My security cam app opens in tandem with the Rachio app, when someone approaches my door, this gives me an instant "soak" option. Hahahahaha!


I have lots of PVC left over (and 150psi air supply always energized in the garage). Squirrels rip the stuffing out of my patio seating cushions when it cools off, I need to make one of these to resolve the issue in a fun way.

Hee, hee, hee......lots of good info on the internet to build these cannons, and how to modify the valve. I made it a rule not to use anything greater than 80 psi.

Yep, the squirrels ruined the cushions in my patio furniture too. Paybacks a 8itch. :D

Note: You can use a razor blade to put a small slit in a tennis ball, fill the ball full of pennies and THAT ball will punch a hole in 1/2" plywood.

Or, combine the P99 and PPQ M2....mix and match, such as a PPQ M2 Q5 frame, P99 AS sear and trigger assembly and Magnum Research MR9 4.5" upper. Oh, and a Beretta 20 round magazine and Speed Sights :D



With holster....had to open up the end just a little bit. :d

All these suggestions and linked thread really got the juices flowing...

It seems the biggest issue for mounting an optic on a P99 AS is the decocker. The optic plate and the custom cutout for it are great solutions. However... what if there were an aftermarket part (sear? trigger bar? not even sure which part would be needed) that would allow the weapon to be both cocked into AS mode (just like the P99 AS) and decocked (just like the P99Q) by moving the slide?

I know this is extremely nerdy, but you guys seem to enjoy doing stuff for the heck of it. My kinda people, those who would build a tennis ball shotgun out of PWC and a compressed air reservoir...:cool:

P.S. The MR9 is indeed pretty cool, I've seen them online before but never in person.

Easy answer. There's not. <img src="http://www.waltherforums.com/forum/images/smilies/eek.gif" border="0" alt="" title="EEK!" class="inlineimg" />
Hmmmm. So which part gives the P99Q it’s nifty decock / cock functionality just from operating the slide? Would that be the sear assembly?

I wonder if there is a source just for the parts that make that possible on the P99Q...

Fonz, I don't have a clue what you're talking about.

There have been post on this forum about how to decock/cock a PPQ by manipulating the slide.

Sorry buddy, let me try to explain.

In another thread, someone posted a video of the ultra-rare P99Q (not the QA). When you fully actuate the slide, the striker cocks. When the weapon is cocked, if you just barely actuate the slide, it decocks. There is no decocker button like we have on the P99AS.

I’m trying to determine if there is a way to replicate that functionality with pistols and parts available here in the U.S.

Someone else here managed to purchase a P99Q upper, and there was a thread about it: https://www.waltherforums.com/forum/ppq/116966-acquired-complete-p99q-9mm-upper-no-lower-2.html#/topics/116966?page=1

However they never gave us a full report as to whether they got the build working like an actual P99Q. I’m curious if it can be done.

From what I'm reading, the P99QA and the P99Q have a very similar trigger mechanism. Both have a precocked striker, requiring a pull of the trigger to complete the compression of the striker spring prior to releasing. Much like a Glock.

So, all the slide movement does is partially cock the striker. I don't have a P99Q or a P99QA, but I'd think that it might be possible to decock the 'partially cocked' striker on the P99Q and P99QA in much the same way I'm able to decock a PPQ.

I can recock the PPQ by simply moving the slide rearward about 3/8"...that'll reset the single action sear, and hold the striker in a fully cocked position. This may also work on a P99Q or QA, but the striker will only be partially cocked.

P99QA (Quick Action)
This variant has a Glock style trigger system with a pre-loaded internal striker. When the trigger is pulled, the striker is fully cocked and released, firing the pistol. The trigger travel is approximately 8 mm (0.3 in) with a trigger pull of approximately 38 N (8.5 lbf). The trigger pull is consistent in length and force from the first shot to the last.

P99Q
The P99Q has a partially pre-loaded internal striker trigger mechanism that conforms to the Technical Specifications (TR) of the German Police. When the trigger is pulled, the striker is fully cocked and released, firing the pistol. Trigger travel is approximately 13 mm (0.5 in) with a trigger reset of 6 mm (0.2 in) and a trigger pull of approximately 32 N (7.2 lbf). The trigger pull is consistent in length and force from the first shot to the last.

Wait... you can decock a PPQ? How?
