I finally decided to have my HK45C, which I have had for quite a while, converted to the light LEM. Rather than try to do it myself due to an understanding of my personal limitations, I sent it to HK after talking to Travis and receiving a RA. One day after sending the pistol, I got a call in the morning saying they were working on it and asking if I wanted the safety removed. The afternoon of the third day it was back at my home with the LEM installed. I have yet to be disappointed by HK Customer Service.
