Thanks, I thought it was just mine that didn't seem to fit right. The rubber ones fit great on my 586. So I got a nice wood one without finger groves, but it has that gap you speak of. I was wanting a set of Miculek grips that are also made by Hogue I believe. Does anyone know if they have the same gap problem? I have never tried Pachmayers, so I can't say anything about them except that I personally just don't like the way they look compared to the Hogue.
