I would like to thank Duane for his great service yet again as well as 3% Engineering Works. I bought a set of sights for my Glock 29 from Duane a while back made by them. Got my license the other day, fitted the sights and went to the range. I kept grouping low and at first thought that I was flinching. I had a friend try it, same result. I took the sights off and fitted the stock sights, shot right on target. I contacted Duane with little hope that he would sort it out but he offered to fix the problem or refund me. I was really surprised. He then contacted 3% who contacted me and will now replace the front sight at no extra cost to me. Thanks for helping Duane!
