Is appendix carry considered crossdraw? Your not really sweeping anything if you pull up rotate forward and to me its always looked the fastest. When Im driving to/from work my 442 rides tucked in my waistband right in front.
No, appendix carry is on the the strong side if you are right handed.
If there were one perfect way to carry a gun, somebody would be rich holding the patent on the perfect holster. Every individual, every gun, and every situation is different. What works for me may not work for someone else. I try to evaluate the situation, such as spending 8 hrs in a vehicle, -vs- standing around for 8 hrs, -vs- whatever I anticipate doing that particular day. I have holsters that I can carry IWB, strong side, on the ankle (which is great in the winter in a vehicle...every try drawing from the strong side wearing a parka with the seat belt on??? Not a great plan!), and other places.
I know there are arguments for always carrying the gun in the same place so you develop muscle memory, but there are exceptions. My Idea of the basic principles of lawful concealed carry involve carrying the gun so it is safe, accessible, and concealed from those who could use the knowlege that you are armed to your disadvantage. Comfort is an issue, but not in the top three for me. I'd rather be uncomfortable carrying a larger gun than totally comfortable carrying a .22 in my pocket.
Evaluate your circumstances, think things through, and figure out what works for you. You are responsible for the choices you make, so make sure that they are the right ones for you.
