Cool man, I'll keep you updated. Immortal Revolt rules for releasing this. I wish I could ask him some questions.
I've also got a design in the works for a spring loaded extractor. The 1911 style one works but can scrape the shells a bit, or at least it does with how I made mine... I have also modified the Mendendez v3 magazines to fit in the Rogue-9... I'm thinking metal feed lips plus an anti-warp carbon nylon on the mags and you'll be able to keep them loaded with ~15 rounds indefinitely without the spring pressure eventually warping... I'm wondering why the two bottom 4mm threaded guide rods weren't moved out to the sides to avoid intersecting the can. On the subject of can, the docs said there was another option to be released in late 2025 but haven't seen anything... Finally, and a super simple fix, I added a 3mm steel rod from the materials list to reinforce the mag release. It's a known issue on FGC9 style lowers that it eventually snaps out under spring pressure.
