I have one of the Advantage Arms conversion kits for my Glock 19, and it is very accurate and reliable. I shoot Remington Golden Bullets through it, as is recommended for plinking, and CCI Mini Mags for better accuracy. I even shoot the 60 grain Sniper Sub Sonics through it reliably. I've poured thousands of rounds through it and probably only had a dozen malfunctions. Not bad for a .22. <img src="/ubbthreads/images/graemlins/thumbup.gif" alt="" />
