If I knew I was going into a gunfight, I’d actually choose to wear a bullet-proof vest and have a long gun instead. Better yet, I’d avoid the whole situation. In reality, the gun should be as comfortable as possible. Trust me, you will notice it is there and it will take getting used. But it should be at least somewhat comfortable or you will not ever carry it. There is an old saying that a .22 on you is better than a .45 at home in a drawer. The real challenge here is finding a comfortable way to carry your gun. Good, quality holsters are expensive so it does not make it easy to test different ways to carry. Talk to other gun owners, read online reviews and ask at gun shows or gun stores. Everyone will have a different opinion; try to find the option that will most work best for you.
