I ordered some Glock factory night sights from Lone Wolf Distributors a while back. I received the sights along with a few other parts I ordered as well 2 or 3 weeks ago. I installed the sights myself and took my G22 out to see how it was shooting. I found out it was shooting about 1 1/2" high. I then took my stock plastic sights and compared the height of those to the new sights and found my rear sight was higher than my stock plastic sight was. Then I noticed the rear factory glock night sight was for a .45/10mm according to the lines on the sight. I went back to the house and looked at my invoice and it said I ordered a 6.5 rear sight not a 6.9. I wasn't happy about it so after putting my plastic rear sight back on I emailed LWD to see if they could resolve this problem for me. I read on a piece of paper that came with my parts that they could only be returned if in unused condition. I was honest about it and told them that I had already installed the 6.9 on my G22. Also that I didn't notice it was the wrong sight until after a trip to the range. Then a day or two later I noticed a email saying they sent me the right rear night sight and had a paid postage envelope included so I could send the 6.9 rear sight back. I got the new rear sight and it was the right one. I am very impressed with LWD that they will take care of their customers. I will be buying from them again and would recommend them to any of my friends. BTW if this isn't the right place for this please move it. Thanks!
