I agree. Even a basic pistol 'accessory' such as the non-SBR 'brace' CAA offers (i.e. Micro Roni) can significantly increase accuracy, target acquisition, and follow up shots on target within a relatively confined environment; while allowing additional accessories (red dot, flash light, sling and whatever else floats your boat).
Don't want all the added 'accessories'? Just pull out the Glock and use it as a standard handgun. As gimmicky as something like this appears to be, it does instill a greater confidence in terms of being able to hit a target in a potentially dark, chaotic, and stressful situation where you may also have loved ones in proximity. The CAA stabilizing brace certainly has it's flaws and downsides, but I'm referencing this as example. Shooting this thing is fun as anything I've shot, and it is far more accurate than I'll ever be.
