PPQ Threaded Barrel/Heavy Spring

Just got the Walther threaded barrel kit for my PPQ and it comes with the heavier spring for suppressed fire. Instructions state to not use a suppressor with the standard spring, which makes sense. But they also say to not shoot unsuppressed with the heavier spring. I suspect the only issue might be not enough pressure to cycle. Or is there another 'secret' reason why they make that recommendation?

Nice looking kit. I just emailed walther CS to inquire about them offering a similar kit for the 5 inch models.

If they would offer a 5 inch ported & threaded factory barrel kit I would be all over it.

using the regular spring with a suppressor provides a lot of shit blowing back into your face... unfortunately, i had once forgotten to change the spring and it was too uncomfortable to shoot.

i agree - there is an aftermarket Walther threaded barrel, but i haven't tried it. would love to have my 5" slides and/or my Q5 with a can.

http://www.jarvis-custom.com/shop/wa...istol-barrels/ This is the route I have been considering. This place offers porting as an option so I was thinking that may help with gas to the face while suppressed.

Anyone know if porting a threaded barrel would be a good idea?

That makes complete sense, but what about the opposite: if you shoot unsuppressed with the heavier spring?

I would imagine plenty of FTEs/FTFs

It might be just fine. HK is also known for putting heavier springs in almost all of their Tactical threaded guns (maybe it's a German thing), with a few exceptions like the HK45CT. I have a USP Tactical 9mm, which has a stiffer spring, and it runs perfectly fine unsuppressed (no 9mm suppressor yet).

Walther CS told me there might be cycling issues. As I suspected. Not enough pressure to cycle with the heavy spring. I'll just try it as an experiment.
