It does this on all 6 GG mag's that I have. Its so weak that the slide never locks back anymore. I've replaced most of the internals with no success. I put a tight bore barrel in, a new piston head, new hammer, hammer spring, sear and valve knocker, bucking, nozzle and the valve thing that's inside it. Nothing helped, I replaced these parts one at a time and functioned after each part change. If anybody has any ideas it would be very helpful.

Could be the leaf spring that isn't bent properly.
