Yeah the website does say that, I called HK about it... They said Lem is available as an option on if someone orders them.
The Lem rocks, i am debating on coverting my HK45 fullsize and p30l.
DO IT!
Some day when I get an HK45, I'll be doing the same light LEM setup. I'm sick of the DA/SA nonsense, at least on carry guns lol.
