I dont have a time from seated AIWB, but I cant see that its going to be that much different. In the past, standing and moving, I was usually right around 1.5 to 2.0 seconds or so, depending on the time of year, and what Im wearing. Its a tad slower in the winter with an anorak and fleece. Its still a lot easier/quicker than trying to draw from 4:00 or so, where I used to carry.
Seated, the draw is really no different than standing. With your hands in your lap, your gun hand is right at the gun, and the other hand clears your shirt, or whatever at the same time your hand is on the gun. The gun sits vertically, and quickly comes straight up out of the holster, with very little telegraphing or reaching and trying to clear what you're wearing.
I normally practice presentations every night after dinner using people on the TV as my target. I have used a timer here too, but not normally anymore. I used to set the cycle to beep at 1.5 seconds and usually have the gun on target and "fired" at, or just before the beep. I think trying to hit the person that pops up on TV and is often there and quickly gone, is a harder goal.
I haven't timed the Smart Carry draws. Since the covid thing, and retiring in the meantime, the need for me using one has been less and less as I normally used it at work. I do still practice with one once or twice a week in dryfire to stay fresh with it. Ill have to look for my timer and see what it actually is.
In the past, I also used to draw and shoot from it in practice a couple of times a month when I shot my 26. There is a bit of a downside to them when reholstering, and with live ammo, I normally open my pants and carefully reholster, which tends to be a bit of a pain having to do it each time you draw. But, doing so is a lot easier and I think safer, as you can see what you're doing. The maker says its easily done without going through all that, and yea, it sorta is, but I dont find it to be that intuitive to do, and is a bit fiddly, and you really cant see what you're doing.
Carry wise, the Smart Carry is a lot like AIWB, but just a little deeper. One advantage is, you dont have a cover garment to clear, your shirt is tucked in behind it, and when standing, you just slip your hand behind your pants at the belt buckle, and the gun is right there below the beltline. Unless you have a "Dunlop" there's nothing in the way.
The gun also sits vertically when sitting and isnt pinched past the bend of your legs like gun carried in a pocket usually is.
Hooking your off thumb and pulling the front of your pant forward slightly, and leaning back slightly does make it a tad quicker and easier, but you can still easily do it serendipitously.
As far as strong side hip carry (or anything else for that matter) vs AIWB, I think you're going to find youre wishing you switched a long time ago, once you try it out. Concealment is so much easier/better and with easier/quicker access, and you can protect the gun much easier.
The Smart Carry is more of a specialty holster, but one holster I will never be without now that Ive used one. It will let you easily carry in clothes you normally wouldn't even consider, and with a gun most will say no way, and its comfortable and easily accessed.
