PWC - 9mm and 5.7 - Q&A (forum.guncadindex.com)

(slightly older beta versions in the picture)

Hey all!

Because the "PWC: DLC" (DownLoadable Content, for you boomers and non-gamers) will be releasing soon, I figured I'd make a post and open up a general Q&A about the PWC.

Questions are not limited to the DLC, 9mm, or 5.7 - all questions about the PWC are welcome!

For the either (but more focused on the 9mm) what's the estimated longevity on these? I know the DB alloy had the side plates for some longevity improvements.

Also for packability how does this compare to a DB alloy size wise?

great questions!

as the frame is designed to be FDM printed, the lasting nature of it will be solely determined by both your material of choice and the quality of your printer/slicer.

The 5.7 though, specifically, is HILARIOUSLY low recoil and required the least amount of mass to succeed (and still hasn't ever broke).

The DB Alloy will inherently take up more space as it has both a magwell and a pistol grip / trigger guard for the AR FCG it relies upon. I wouldn't get too hung up on the side plates - they were a pressure vessel containment strategy that looked VERY cool, but were ultimately overkill for what absorbs energy (the trunnion primarily, as it holds the barrel and the blast, and the backplate secondarily, as it just bounces the bolt back and forth from the remaining blowback force)

Have you had any failures on the pwc9 yet? I know the question of filament/skill/printer etc is always a topic. Any failure mode to look out for?

I might be looking for a sister for my alloy soonish.

The currently released versions? None. Not one, actually!

Excellent! Great work and they look great
