I've owned the Advanatge Arms conversion kit for my Glock 19 for about 3 years. I've used it 4 times and each time fired hundreds of rounds through it with no issues at all. I used the 22 Ammo they recommended in the manual and the gun worked well. I can't remember the brand they recommended but I didn't stray from their advice.
I found it very slick and easy to use. I'd buy it again based on my experience.
