More rallying for the 9mm.
For small concealed guns, maybe. My little P365 is quite accurate.
But for self defense where I feel confident, the .40 and .45 is my preference. The heavy frames somehow make them more accurate as my aim is right on where as with the smaller guns I tend to shoot left and down a few inches at 50’.
For home defense a semi auto 12 gauge is preferred with the magazine load alternating between #4 bird shot and double aught buck. A Judge is great for bedtime awakenings.
Isn't that common for a right handed shooter with a minor kick flinch?
Lot’s of dry fire practice and ball and dummy drills will help your flinching problem.
