CCW Laser Grip Question

[mkonops]

I'm thinking about getting a set of CT Laser Grips for my Kahr K9. I carry it IWB in a Don Hume holster. I was wondering if anyone here has a similar setup and can give their thoughts on it.

Will the grips affect holstering at all?

Will the tight fit of IWB carry activate the laser inadvertently?

Are these grips a significantly different width/feel than the factory grips?

Thanks.
