Welcome to the forum.
As you can see there is a compromise between conceal ability and shoot ability. There are things you can do with the smaller guns to make them shoot better, for me it means making the smaller gun larger, which to a point defeats the purpose of the smaller gun. I will use my Glock 27 as an example. I choose to run G23 mags with grip enhancers to give me a larger grip and more capacity, I find it carries better AIWB.
My rifle and pistol are tools, I am the weapon.
