I appreciate all the comments. I have a number of big guns but I think now I'm gravitating towards small carry choices and revolvers more...not sure why at this point in my life. While I know that the guns aren't primarily used at the range, the only way to get good at using the firearm is by actually firing it and often. So, I do want it to be comfortable to shoot for long periods and that's why I'm getting the PPS 9mm the 640 pro, and hopefully soon, the Sig 938. Thank you for all the feedback.
