if you have a case separation first thing to do is pull the gun apart and give it a good shaking out. turn your frame upside down and give it a few good taps on the bench.
gunpowder getting caught in the lift mechanism could inhibit proper movement.
when you get home and do your cleaning out, use a spray can cleaner like clp. work the lift mechanism with you finger as you spray into and under it.
drop your unlock block and inspect your anti-seize to make sure there is no unburnt gunpowder in it. if so wipe clean and re-apply.
make sure to avoid those rounds, and it always helps if you drop a range report in this thread calling out the poor round.
Maybe the loose power is the cause.
Because most people's gun have been registered. So government will adopt a way to manage these guns if there is a separation.
