Black Widow grip movement

[engtee]

Hello all. Although I have owned a mini .22 mag for about 15 years, I recently purchased a Black Widow. Irregardless of how tight I make the grip screw, the grip rocks back and forth. I do not want to alter anything permanently, but would like to stop the rocking. Any ideas?
Also, this is a conversion, with adjustable sights. I have been looking for a pocket holster that will stay in the pocket, when drawn, but have only found some for fixed sights. Any suggestions?

You have factory "oversize" rubbers on your BW, yeah?

Squirt a drop of silicone caulk (bathroom tile style) on each grip before install, wrap in a cloth and clamp somewhat firmly for the cure time.

They're not moving now, and they're not so bad to remove as the rubber has a bit of flex to it. If you are using hard material grips, barely use any silicone at all or else you'll destroy the grips during the next removal.
