I see the pics of the new Glock having grip adjustment inserts. I'm glad they finally got around to doing this after seeing how well it worked on other guns. My question is, is the smallest setting equal to the current frame size or will it be smaller (I hope!)? I have owned a G20SF and a G21SF. I got rid of them both because their size just does not work with my hands. I should have learned my lesson with the first gun, but I really wanted it to work. Will the 4th generation G20 and G21 (and SF if they still make them in the new frame) have smaller grips than the current SF models? Right now I am waiting for Lone Wolf to make its Glock compatible frame in the large size frame because I know it will be smaller. I would consider getting the Glock 4th generation if I knew they were smaller. Thanks.
