I would like a P30sk with the light LEM but pretty hard to run across.
I’d like to know why one couldn’t get a LEM if they got the safety
I don't believe HK offers it with a safety option because the largest single buyer of LEM guns was Customs and Border Patrol which are phasing HK out for Glock 47's
And since there is no Cocked and Locked used as well as letting off the trigger is the decocker on a LEM adding a safety is probably not feasible.
You can have a LEM with a safety, just not from the factory. Start with a pistol with a safety/decocker, convert to LEM and keep the safety lever.
