I had a grip reduction on my G30 to better fit my hands. While it significantly reduced the overall grip size, the backstrap and trigger reach remains about the same. I understand that the Glock 30 Short Frame and Gen 4 models have a reduction in this area of 3mm to improve trigger reach. Has anyone attempted to remove this excess material in the backstrap on a Gen 3 model. If so, I would really appreciate your insight on about how much material there is to work with or if this is even possible. All comments are appreciated. Thanks.
