I've been working with mine, especially trying to sell the draw and make the production of the pistol look as much like not presenting a gun until the last crucial moment as possible while looking at impacts on accuracy. Mostly dry work with some validation on photorealistic targets using actual bb's.
To be perfectly honest, I'm kind of glad to see this specific work behind a paywall rather than out in the open. It's a potent force multiplier for a subset of common street crime...but it's also basically robbery college if applied the other way.
And hopefully that move also helps prevent some vainglorious dumbass from youtube from misappropriating the work so he can make his next luxury car payment.
