After quite a bit of research, and good information from "The Esteemed Dentists", I have decided to move into this model (S&W M&P 2.0 Compact) after about 35 years of using Glocks (17, 19, 21, 30).
The largest criterion that is moving me is for the manual safety availability. If that were not an issue, there would probably be insufficient reason for a change. That there are skilled and reputable users on this site (Drs. Roberts and House) helped my decision, which was not an easy one.
Thank you all for the information that many have provided.
