Without a doubt my most reliable autoloader has been my Gen4 Glock 27. Picked it up for $425 through the GSSF program. I have about 2,000 rounds through it with many types of ammo without one failure of any kind. I have used the standard 9rd mags with and without various extensions and 15rd mags. Not a single problem. A friend has had the same results with his Gen4 27.
Second place would go to my Sig P220 Elite Stainless which is significantly more than $600. Not a single problem with the standard 8rd mags but I have had problems with the 10rd mags.
My Rugers/Kimbers/S&W M&Ps are not bad, but I wouldn't trust my life with them over the Glock 27 or Sig P220.
