I dedicated 2-3 years to the LEM in two P2000's and a P2000sk. By the end of that, I loved the LEM and shot it pretty well, by my standards, anyway. But I remained frustrated by the difficulty mounting a dot. So I switched back to Glock 19's early this year.
I still get nostalgic about the HK's occasionally, so last week I dusted off the P2000 and shot it side by side with an iron-sighted G19. I found that I vastly prefer the G19 trigger now.
