I am right there with you. 90% of my carry is with a G26, 10% with a S&W 642.
99% of my pistol training are with those two guns.. if it is your normal you don’t have a problem running it or a larger gun. The same cannot be said for the other way around.
I’ll say it until the end of time... you are the weapon. But, spending your paycheck is easier than putting in the work so there’s that.
