I've been converting my usp40 2023 production da/sa to light lem with the universal kit and everytime i get the frame fully assembled and cock the hammer the hammer strut pops down and out of place and the trigger goes dead. i haven't been able to find any answer to this online so i hope somebody here knows what the issue is thanks.
