Get a CZ, preferably a 75 or P-01
Here is an interesting article on the P-01:
In 2001 the Czech National Police asked a number of gun makers to come up with a new duty gun to meet their stringent requirements. So stringent were the requirements that many gun makers decided not to participate in the design competition.
The gun had to withstand 4,000 dry-firings, 3,000 de-cocks, 1,350 user-level disassemblies and re-assemblies, 150 complete disassemblies down to the springs, screws and pins, 54 drops of 1.5 meters on concrete, a 3 meter drop, and a 24-hour freezing test.
With the easy stuff over, the gun had to be stripped of all lubrication, submerged in sand and mud and still fire reliably. On top of all that, the National Police required a 15,000 round 9mm +P service life. Further testing revealed that the P-01 could easily survive more than 30,000 rounds of 9mm ball ammunition.
In way of comparison, the U.S. Army had a requirement for 115 grain, 9mm ammo of 495 mean rounds between failure (MRBF). The Czech National Police requirement was 500 MRBE During the P-01's testing, the average number of stoppages was only seven per 15,000 rounds fired. The MRBF was an astounding 2,142, which exceeds the requirement by nearly five times.
