I have been carrying my Ruger RAP 9 Compact for the last several days! Damn, I love that gun, and it's a great shooter, even if it is heavy!
Butttttttt, when it comes to comfort and balance in my hand, the S&W M&P 2.0, 3.6, wins hands down. And it's a beautiful gun also. Lighter, too! I is slightly more comfortable next to my body than the RAP.
Next up in the rotation is the Taurus PT111, the most comfortable gun, next to my body, in the drawer! It is also a good shooter, and has never failed me!
It sure is nice to have dependable choices!
