Owned a CZ 75. It never failed in the 3000+ rounds I owned it.
Had a Taurus PT 92. It never failed.
I've never had a Ruger fail, or a Smith and Wesson or, for that matter, a Glock.
I've played with a Berreta, a BHP, and a Tanfoglio; they all choked. As a matter of fact, not only would the Tanfoglio choke, it would, on occasion, and quite unpredictably, go full auto!
A Witness, on the other hand, never gave me any problems.
So, based soley on personal experience, and IMHO, the most reliable 9mms are the CZ 75, Taurus PT 92, Glock 17, S&W 910, and the Ruger P95 (I know, != 3).
