I don't know what else to do, but to take my guns to the gunsmith, and quite frankly for such a minor task I would hate my own guts. The gun is DanWesson Guardian 9 (and I have a VBob 45 ready for the same mod). I didn't like the slim grips it/they come with (because they are slim, they are actually nice). So, I bought new Carbon fiber slants, standard size and upon the rep suggestion, I bought also new bushings and standard screws. I also bought the Brownells removal tool. Applied heat, as suggested here elsewhere, and these things don't move and the bushing is beginning to deform. The good news is that the old bushings can hold the new grips with the standard screws, but I suspect barely. So, any further suggestion? Do you know if I take them to the gunsmith what will they do differently? I don't want to risk any damage if they have to drill or something. Thanks for your help.
