I ordered a 2nd set of Tru Glo Pro Series iron sights for my Mossberg 935 recently. I have a set on my BPS 10 ga. and really like them. When I installed them I found the windage adjustment allen screw would not tighten or loosen...apparently bad threads. I took the windage part off my Browning Pro Series sights and installed on the 935 to get me going so I could pattern the gun and sight in.
I e-mailed Tru Glo customer service from their website this Sunday. Yesterday afternoon (Monday) I rec'd an e-mail that they were sending me the replacement part out right away.
That's the kind of Customer Service I like to see, answer and solution the next day!
