After deciding I was going all in on an RDS on my 1911's, I did a fair amount of research and shot a few classes with a TRP Op I picked up locally that had a CHPWS cut and cross plate with a Holosun 507c. No rub on C&H but I much prefer a direct mounted optic. After researching again and making some phone calls, I went with Green Tick Tactical Solutions. I could not be happier with the results....communication was excellent, price and work was outstanding, and turnaround time was super quick at approximately 3- 4 weeks. I have sent 5 DW 1911s to GTTS and all have been perfect on return. I have run more than 2K rounds through each of the pistols and the optics have been rock solid on all of them. I almost hate to recommend them as I don't want their turnaround time to go through the roof, but Jesse does such good work he deserves the business IMO.
