I keep missing the business hours to speak to a HK rep so I figured I'll just ask on here. I finally decided to go straight LEM. For those that sent their HK's in for a conversion; How much does it cost to send it in, convert to LEM, and get night sights? Has anyone had HK gunsmiths fit Heinies or Trijicons to their slide? Also I hear that the turnaround can be quite fast. Should I expect a fast turnaround?
