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.
Yeah, most of it. For the parts that need to be metal, you can order "replacement" parts. Guy in the gun store clued me into this as a money saving trick.
