Absolutely! I took a class two years ago that we were having to slide down the chair to “straighten” to be able to draw from AIWB. I use that method when drawing from my pocket. If I haven’t moved my pistol from front pocket to cargo pocket, the easiest sitting down draw for me.
To think you are going to sit there when an event occurs, is not thinking things through. 99% of the time time I’m sure I’m going to be count the floor tiles and trying to get into the grout! LOL me no stay upright for possible incoming from unfriendly.
I find that those who preach “one weapon one place always”, tend to be more game shooters. They worry about times, since that is what there status is based on. Shorter times, means higher status. There are no timers in the real world, as Clint Smith said. We aren’t going through a preplanned course that we have walked through and have mentally figured out our plan. We have to gather information and make the best possible shot with that information.
And this is no dig at comp shooters, as I be one. But I keep games and the real world separated.
