** (02/11/15) If you are interested in the PPQ, be sure to check out the PPQ case study on its sear mechanism
I’ve been hearing plenty of nice things about the trigger on the Walther PPQ, and it’s been a long wait for the 5″ version to be back in stock. The new gun finally arrived today, and the trigger certainly didn’t disappoint.
PPQ’s factory trigger weight is 4.5 pounds, but unlike the 5 pounds trigger on my HK P30, the trigger on the PPQ is so smooth that it felt like a 3 pound trigger, with no increase in trigger weight right before the break, something the P30 and SR22 both couldn’t avoid.
If this is my first gun I would be perfectly happy and be shooting away with the stock trigger. But having done 5 trigger jobs already, I couldn’t help myself but to bring the PPQ’s trigger down to 2.5 pounds like all my other guns.
First I must say that I’m extremely impressed with the PPQ’s internal design. Maintaining this gun is way easier than any of my other handguns because all the main parts are contained in a “gear box”. After pushing one spring pin out, the gear box can be pulled out and you have instant access to all the main parts. Hats off to Walther for this wonderful design.
* All the major components are easily accessible for cleaning just by pulling the gear box out. Awesome design!
Like any new guns, there was a gritty feel as the trigger travels. An issue easily solved by firing thousands of shots, or by polishing the parts that come in contact with the frame of the gun
Polishing The Trigger Bar
The trigger bar rides underneath the sear housing assembly. I’ve colored the the part that requires polishing in silver in the picture below.
Here’s a photo of the trigger bar from the factory. The part is stamped and you can see the stamp marks which can cause a lot of grittiness. On the right is the same part after polishing with a fine sanding stone, a rubber polishing bit, then with polishing compound.
Another place to polish is the dimple on the side of the trigger bar, as well as the entire left side of the trigger bar.
Polished out the areas that cause the most friction. Now the trigger travels smooth as silk.
Polishing The Firing Pin Stop
Since posting this guide 2 years ago, I’ve learned that some PPQ’s suffer from a gritty trigger not from the trigger bar, but from the firing pin stop that is riding too tight against its housing. I was lucky enough to not have that problem, but I’ll post some pictures on how to remove the firing pin stop pretty soon.
Polishing The Sear
The sear engagement surfaces can be polished to further reduce the trigger weight. Note that this part is a preference as some people like a smoother break, while some enjoy having more of a wall, or a bit more force before the break.
The engagement surface to polish is pointed below:
Lightening The Trigger
I’ve written a more updated guide on replacing the spring and lightening the trigger. The guide is below:
PPQ 3.5lb mod
Reducing The Creep
Since first writing this guide I’ve came up with a fully adjustable and reversible method to reducing the creep on the PPQ. The guide is below:
PPQ Adjustable Creep Conversion
This trigger job will make your PPQ perform unlike any other polymer pistol. Many members of the Walther forum had made these mods on their PPQ and some are shooting on a competitive level with no failures. I’m happy to see many getting the most out of their PPQ, and hope you would be amongst them.
