The AA kit is very nice, I have one on my 17. It's the same model kit for both the 17 and 22. It's fussy on what ammo it likes and I'm not a fan of the OEM Glock plastic front and rear adjustable sight.

It functions very well with CCI Mini-Mags and Remington Golden Bullets. It works decently with Remington Thunderbolts, but does foul up a lot quicker with them.
