If you have an ambi safety with a right side lever that wiggles or moves independently of the left side it usually means there is a problem with the connection. With Kimbers (and really most all ambis), the two parts are joined by a tongue and groove type connection through the grip safety. Usually what happens is the tongue (left side) was filed too much or the groove (usually the right side) has started to expand allowing the movement. I would take it apart and fit the two and you should be able to see how much movement there is. A quick fix can be to carefully squeeze the groove portion together for a tighter fit. You may also check with Kimber and see if you can get a replacement but it will have to be refit to your sear.
How do you take it apart? If I have to get any parts refitted, I'm going with a non-ambi Wilson combat thumb safety and maybe long slide release.
Just got my first 1911, a kimber but since bringing it home, the thumb safety became loose on the right side of the gun... any ideas how to fix this?
