I have an advantage arms kit as well after waiting for a ciener kit for a year and they finally refunded all my money.
I like it.
Use the suggested ammo brands and you'll enjoy it. Same with above comments on advantage arms mags. while testing other ammo, It has problems with federal bulk pack (red box) feeds the recommended types with no issues and so, far the winchester white bulk pack is working well. I have 4 bricks of older rem-gold that i set aside for it and it runs through those without breaking a sweat. all of my issues have been FTE with the spent casing getting caught as the slide cycles the next round. removing the slide for cleaning can be a challenge, or at least is for me, due to the release lever groove being really tight with the Adv Arms slide. The factory glock slide has no issues on mine. I consider it a quirk.
If I ever had to replace my conversion I'd get another adv arms one
