Bad design - Kensight DAS Adjustable Rear 1911 Tritium Night Sight

I ordered this sight set for my Gordon MC 1911 SC. I never tried to install the front sight, but it didn’t look like it would fit by eyesight. The rear required fouling for fitment in the dovetail. Once I got the rear installed, the windage would not hold zero. I was not impressed with the design for duty level use because there were moving parts exposed. I don’t think the quality is there for any type of use. I emailed customer service at the company, but never received a response. I would not recommend this brand or model due to my experience. There are brands with better quality and customer service.
