It would be nice for you, if you found another shooter who owned the G26/27. As you will find that your small pinky finger will hang under the grip unless you have an extension for it. I had a G27, and enjoyed it very much and regret ever selling it off for something else. I found it to be quite accurate, if I did my job. Keep searching you will find stats for officer involved shootings with the 40 S&W, and I don't think you will be disappointed. The G27 was my BUG, as I carried the G22 on duty myself.
There really is nothing wrong with the .40 S&W, as shot placement is everything.
