I have a FNS 9C that I've owned for years. I've always shot it as accurately as any of my other guns. FNS had a recall on the striker assembly (they termed it a voluntary upgrade), and since I received it back from the recall it consistently shoots low and left. I've been to the range with it and a number of other guns and the FNS is the only one I have this issue with, so I don't think it's me. I've measured the sights with a caliper, and they are centered. It comes with two back straps, and it has the same issue regardless of which back strap I use. I have a potential buyer for it but am holding off selling it as I'm not comfortable selling a gun that may have an issue. I spoke with FNS, and they're telling me they did nothing to it that would cause this problem but they're willing to take a look at it. Before I take the time to send it in and take a day off of work to wait for it when they send it back I was wondering if anyone has a suggestion as to what may be causing this.
