Walther P99 9mm, 4000-5000 rounds so far, ZERO malfunctions (EXCEPT the one time I -- me, the shooter! -- didn't shove the magazine in all the way and the first round fired, but the next one didn't feed because the mag had dropped down a bit -- MY FAULT). I've been shooting some WWB, but mostly inexpensive Monarch green box from Croatia ($5.86/50 at Academy). Gun is absolutely reliable, compact, light weight, wonderfully balanced, very accurate, and offers side benefit of being customizable to hand size.
Also Walther P-38 WWII war trophy, completely 100% reliable AS LONG as 8-round mag is loaded with only 7 rounds. Think that after 60 years, it may need some new springs, but given 7 rounds in the mag, it, too, has been 100% totally reliable. I've probably put 1500 rounds through this one, and need to retire it because it's in great shape and all the numbers match...http://www.thehighroad.org/images/smilies/smile.gif
