I've fired hundreds of rounds out of my Glock 19 Schnitzel without issue.
And I understand that not everyone can get their hands on a high quality "real" parts kit, but it's not just frames that have come a long way. But even the single shot guns have gone a long way!
I've got a Harlot with a dime breech that I've put dozens of (admittedly .22 short) rounds through. You can build one of those for like $20-$30.
There's plenty of other awesome builds that can withstand hundreds or even thousands of rounds, made out of good ol' PLA+.
Balancing my desire to post cool photos with my OpSec desires. Might set stuff up for it soon.
You can make the part that is legally considered a gun. There is one guy that made a completely PLA gun, but it used special custom ammo.
There's multiple designs that just need a trip to the hardware store to complete.
dang, a pla lower receiver
what a time to be alive
