I have a 22 LR conversion for my Glock 23 by Advantage Arms. Federal Auto-Match is the worst for mine. Federal Bonus pack is acceptable but still has FTEs. CCI-Mini Mag and Stingers work well for my Walther P22. 150 rounds without one failure. I have to buy more ammo to see what works best for the Glock conversion. What is your absolutely best for reliability? Edit: This is the list recommended by the manufacturer: Wanna kill these ads? We can help!
