P90 mag catch replacement

thingiverse

I have been using this Jing Gong P90 for nearly a decade without ever encountering any issues. The internal components have undergone significant upgrades, but the outer casing has taken a beating over time. A critical failure occurred when the magazine catch broke in mid-game, and sourcing replacement parts proved to be a major challenge due to their high cost or scarcity. Marui parts were the only viable option available to me. Unsatisfied with the existing designs on Thingiverse, I decided to create my own magazine catch from scratch, making it slightly larger and more robust than the original. I pinpointed the weak point where most of these components tend to fail and reinforced it while also enlarging it to facilitate easier operation. The slope and radius of this custom part were meticulously matched to mirror the original as closely as possible. So far, my creation has performed flawlessly, albeit with a minor requirement for some sanding on the slope to ensure smoother functionality. Nevertheless, it is now possible to forcefully insert and remove the magazine with ease, just like before.
