I saw on another post that a dude put a black grip on a FDE 2022. It looked cool so I wanted to be cool too and did the same. But.... The black grip shifts just slightly and clicks when I grip the pistol.
Did I put the grip on wrong?

Possibly. The other possibility is that the grip was made not quite to specifications. My E2 grips for my Sig 229 never fit properly. I sent them back to Sig and the replacement E2 grips had the same problem. I ordered G10 grips which were affixed with screws and things have been fine. What kind of grips do you have?

I ran into this with my Sigpro as well.
Mine came with 2 grips. IIRC small and medium.
The medium one made a slight clicking noise.
I ordered a replacement from TGS and no more clicking.
I believe this is the one I ordered.

Thanks! The one I put on is the medium size. I am guessing the grip fit is not quite right. The shift / click stops when I grip the pistol so its more an annoyance issue than a performance issue.
