I took my Glock 26 to my LGS to have him take the stock sights off and install the Glock factory night sights. He did it and I picked it up. But now, sitting at home looking at it, it is clearly obvious the rear sight is not aligned with the front. It looks like it's way more to the right than the left. This cannot be the way it's supposed to be, right? Should I take it back to the shop. I feel bad if I'm wrong cause the guy told me the machine automatically sets it to factory alignment. Thanks guys, I look forward to your response!
